Which is the correct answer: Higher Hydration energy: Ca +2 or La +3 (same size and electroneg.) Higher Hydration energy:: Sr +2 or Pb +2 (same size and charge) Higher Hydration energy: Ba +2 or Ca +2 (same charge an delectroneg.) The more basic anion: IO 4 - or Br) 4 The more basic anion: BeO 2 - or BrO 4 - The stronger Acid: HClO 2 or HClO 3 and explain why Solution Higher Hydration energy: Ca +2 or La +3 La +3 and Ca +2 are nearly same in size. But the charge density on La +3 is more than Ca +2 due to +3 charge on La +3 compared to +2 charge on Ca + . Hence, hydration energy of La +3 is more than Ca +2 . Higher Hydration energy:: Sr +2 or Pb +2 Here charges are same but size decides the energy. Radius of Sr2+ is 132 while that of Pb2+ is 133. So Sr is small is size so have high hydration energy. Higher Hydration energy: Ba +2 or Ca +2 Barium cation(+2) have more hydration energy compare to Ca2+ due to smaller size. More basic anion: IO-4 or Br-4 IO-4 is more basic due to electronegetivity of Iodine which is less compare to Bromine. The more basic anion: BeO 2 - or BrO 4 - BeO 2 - is more basic due to electronegetivity of bromine which is less compare to Berylium. The stronger Acid: HClO 2 or HClO 3 Most acidic: HClO4 > HClO3 > HClO2 > HClO. The more number of oxygens in an oxyacid, the stronger an acid . .

1. Briefly state the difference between single stage and multistage distillation. (i.e. you can solve this question with an aid of the schematic diagram) 2. Briefly describe the equilibrium or flash distillation, simple batch or differential distillation, and simple steam distillation. Solution 1.SINGLE STAGE DISTILLATION :A single-stage continuous operation where a liquid mixture is partially vaporized: the vapour produced and the residual liquid are in equilibrium, which are then separated and removed. The feed is preheated before entering the separator. As such, part of the feed may be vaporized. The heated mixture then flows through a pressure-reducing valve to the separator. In the separator, separation between the vapour and liquid takes place. Multistage distillation : Method used for sea water distillation. The heated seawater flows to the first stage, where it flashes upon entry. During flashing, some of the water vapour (steam) is removed from seawater. The flashed vapour is then condensed on the outside of the tubes carrying seawater feed to the brine heater.condensed steam is withdrawn as fresh water. The unflashed portion of seawater now contains more salts, and is send to the second stage for further flashing. The second stage is operated at a pressure lower than the first stage in order to lower the boiling point of seawater. At the second stage, more water vapour (steam) is flashed off, and is again recovered as fresh water by condensing on the tubes carry seawater feed to the first stage. The remaining seawater is then send to the third stage, at a lower pressure than the second stage, for more separation. 2.Flash distillation :It is also called single stage equilibrium explained above.. Differential distillation :Batch distillation is an unsteady state operation. It is usually carried out in a batch still to which a column equivalent to a number of equilibrium stages is attached. As in the case of simple distillation, a fixed quantity of liquid is originally charged to the batch still. During distillation, the vapour passes upward through the column. The whole column is an enriching section. The vapour is condensed into liquid at the top of the column. Part of the liquid is returned to the column as reflux, and the remainder withdrawn as distillate. Nothing is added or withdrawn from the still until the run is completed. Simple steam distillation : Steam distillation is a separation process used to purify or isolate temperature sensitive materials, like natural aromatic compounds. Steam or water is added to the distillation apparatus, lowering the boiling points of the compounds. The goal is to heat and separate the components at temperatures below their decomposition point. .

1) Is technology the critical driver of globalization? 2) What is the nature of this arguement conceived by: liberlism, mercantilism, and marxism? Solution Technological developments are considered as the main facilitator and also driving force of most of the globalization processes. Technology is defined as the socialized knowledge of producing goods and services. We could describe the term technology with five important elements: production, knowledge, instruments, possession and change. The definition of technology as a socialized knowledge can be conceived better with these elements. We shall look through them: Technology has something to do with production (of the goods and services). We need technology to produce something either goods (ex: television set, cars etc.) or service (ex: security, teaching etc.) Technology enhances our capacity to produce. Technology has a relationship with knowledge . Technology is an outcome of intellectual activities. Therefore technology is a type of an intellectual property. Nowadays technology is developed through research and development institutions as integral parts of several universities. Technology has a connect with with instruments . Instruments are considered the extensions of the human body, whenever an instrument is used there is technology involved. The instruments show the usage of technology by human beings. Instruments are mostly physical like computers, vacuum cleaners, but sometimes there are immaterial instruments like databases in computer programming. Technology has to do with possession . Those people that possess technology also control it. Controlling technology has something to do with economics and politics. Thus, we speak of technologically rich and poor countries as well as the struggle among them usually in the forms of patents, transfers and protection of intellectual rights. Technology has to do with change . Due to technology, the world has changed drastically. Many of the innovations from the technological advances have important effects on lives of peoples of the world, that has witnessed radical changes more so after 1960 .

1) What creates the US federal government-wide financial statements? 2) Who audits the statements? 3) What is the audit opinion that the statements receive? 4) What do most federal (and non-federal) entities receive? 5) Are there any issues in the government-wide statements? 6) If there are issues, list at least one effort to overcome an issue. Solution Ans-1) IN respect of each & every country there is Administatration department which takes care of the country\'s finance domain. Similarly, for the US government, there is a Bureau called Bureau of Fiscal Services which creates & maintains the financial statements of the US federal government, this statement or financial report contains the country\'s revenues & costs and assets & liabilities (both monetary & non monetary) & this Fiscal Services takes responsibilities of uniformity in the use of accounting standards & reporting requirements ensures the transparent exchange of financial information amongst the government agencies. This, preparation of schedules or summary of monetary & non monetary assets & liabilities, uniform accounting standards & reporting requirements creates the US federal government-wide financial statements. Ans-2) Government Accountability Office, audits the statements. Ans-3) The Government Accountability Office expresses their opinions based on their audit findings, wherein the may provide a opinions without any qualifications (i.e. unqualified audit report) or they may disclaim from any opinions (i.e. Disclaimer Audit Report) or audit opinions with qualification if they have found any material weaknesses or significant inefficiencies or any kind of financial irregularities. Ans-4) The responsibility for preparation & fair presentation of financial statement is the responsibility of management of the federal government however, there are the instances where the federal government is not able to provide the sufficient reliable information or samples for audits to auditors or they have not developed an adequate system of accounting orÂ Â have insufficient appropriate evidence to support certain material information, thereby auditors disclaims from framing any audit opinions with the concrete base for their disclaimer of opinions. Ans-5) Yes there are the issues in the Government wide financial statemens. Ans-6) For example, if there is any material weakness or inability in determining the current or noncurrent assets like properties or inventories or any plant & machinery or a reasonable estimate of the liabilities have not be accounted or there is inadequacy in the amount of assumed liabilities then there has to be robustness in the federal\'s internal control system which will not have any limiting scope for expressing the audit opinions. .

1) describe how temperature influenced what materials condensed from the nebular cloud. 2) compare and contrast the composition of the inner and outer planets 3) explain the frost line and the influence it has on the formation of planets (in any solar system). 4) explain why our solar system has rocky inner planets and gaseous outer planets and identify the most metal-rich planet in the solar system 5) explain the occurrence of Hot Jupiters Solution Solution: 1) During the early stage of evolution , soon after the completion of the cloud collapse , nebula is hot . The mass accretion rate from the nebula onto the star is high . The equilibrium condensation temperature of the Silicates and metal comprises 90 % (by mass) of the condensable solids.The temperature decreases away from the mid plane and away from the Sun. The accretion of gas onto the sun leads to the dissipation of energy . The nebula is heated internally due to this . Condensation metals include Iron , Nickel and Aluminum . Most metals condense into solids at temperatures of 1000 - 1600 K . Metals made up <0.2% of the Nebular mass. 2) The Inner planets are Mercury , Venus ,Earth and Mars. They are all solid and rocky and similar to Earth . Inner Planets are also called Terrestrial Planets . Inner planets are warmer as these are closer to Sun . Outer planets are called Jovian Planets and are mainly Gaseous in nature . Outer planets are colder as they are farther away from the Sun. All Outer planets have rings . 3) Frost line is also called the Snow line or Ice line . It is the radial position of condensation or evaporation front which varies over time . With reference to the formation of the planets, it is the distance in the Solar Nebula from the central protostar where it is very cold to where the volatile compounds like water , Ammonia , CO2 ,CO condense into solid ice grains. 4) The temperature of the early solar system explains the Terrestrial nature of the inner planets . As the gases coalesced to form the proto Sun the temperature in the inner SOlar system rose . The temperatures rose to about 2000 K , so only substance which have very high melting points remained solid . That is why the inner solar system planets are all rocky . 5) Planetary migration is responsible for the formation of hot Jupiters. These are formed in the outer regions and then migrate to the inner regions of the Solar system . It forms beyond the frost line , from rock , ice and gases due to core accretion method of planetary formation . .

1. How are budgets used for a company or in government? What would your suggestions be to balance our economic budget? 2. After identifying suggestions for balancing the economic budget explain the importance of being able to identify various \"variances\" that may be identified? You may use any examples you want. Solution 1. How are budgets used for a company or in government? What would your suggestions be to balance our economic budget? Ans. A government budget is a government document presenting the government\'s proposed revenues and spending for a financial year that is often passed by the legislature, approved by the chief executive or president and presented by the Finance Minister to the nation. The budget is also known as the Annual Financial Statement of the country. This document estimates the anticipated government revenues and government expenditures for the ensuing (current) financial year. [1] For example, only certain types of revenue may be imposed and collected. Property tax is frequently the basis for municipal and county revenues, while sales tax and/or income tax are the basis for state revenues, and income tax and corporate tax are the basis for national revenues. The two basic elements of any budget are the revenues and expenses. In the case of the government, revenues are derived primarily from taxes. Government expenses include spending on current goods and services, which economists call government consumption; government investment expenditures such as infrastructure investment or research expenditure; and transfer payments like unemployment or retirement benefits. A status of financial health in which expenditures exceed revenue. The term \"budget deficit\" is most commonly used to refer to government spending rather than business or individual spending. When referring to accrued federal government deficits, the term \"national debt .

1. How are temperature and heat different concepts? 2. How does the specific heat of water compare to the specific heat of other common materials? Why is this important? Solution 1. There is a fundamental difference between temperature and heat. Heat is the amount of energy in a system. The SI units for heat are Joules. A Joule is a Newton times a meter. A Newton is a kilogram-meter per second squared. Heat is transferred through radiation, conduction and convection. The amount that molecules are vibrating, rotating or moving is a direct function of the heat content. Energy is transported by conduction as molecules vibrate, rotate and/or collide into each other. Heat is moved along similar to dominos knocking down their neighbors in a chain reaction. An increase of electromagnetic radiation into a system causes the molecules to vibrate, rotate and/or move faster. With convection, higher energy molecules are mixed with lower energy molecules. When higher energy molecules are mixed with lower energy molecules the molecular motion will come into equilibrium over time. The faster moving molecules will slow down and the slow moving molecules will speed up. Temperature is the MEASURE of the AVERAGE molecular motions in a system and simply has units of (degrees F, degrees C, or K). Notice that one primary difference between heat and temperature is that heat has units of Joules and temperature has units of (degrees F, degrees C, or K). Another primary difference is that energy can be transported without the temperature of a substance changing (e.g. latent heat, ice water remains at the freezing point even as energy is brought into the ice water to melt more ice). But, as a general statement (ignoring latent heat), as heat energy increases, the temperature will increase. If molecules increase in vibration, rotation or forward motion and pass that energy to neighboring molecules, the measured temperature of the system will increase. 2. Water has one of the highest specific heat capacities known. There are however a few substances whose specific heat capacity is higher A large body of water can absorb and store a huge amount of heat from the sun in the daytime and during summer while warming up only a few degrees. And at night and during winter, the gradually cooling water can warm the air. This is the reason coastal areas generally have milder climates than inland rtegions. The high specific heat of water also tends to stabilize ocean temperatures, creating a favorable environment for marine life. THus because of its high specific heat, the water that covers most of Earth keeps temperature fluctuations on land and in water within limits that permit life. Also, because organisms are primarily made of water, they are more able to resist changes in their own temperature than if they were made of a liquid with a lower specific heat. .

Which is the stronger acid in the following pair? Explain your reasoning. Be sure to answer all parts. p? Methoxyphenol o? Methoxyphenol The stronger acidity is due to (select all that apply): electron-donating inductive effects intra-molecular hydrogen bonding electron-withdrawing inductive effects conjugation with the substituent Solution 1. Ortho-methoxy phenol is more acidic than para Methoxy phenol. Since OMe is -I group and it stabilizes the phenoxide ion. As we know that strength of Inductive effect decreases with the increase of distance. Hence in para isomer, withdrawing effect of OMe is less compared to ortho isomer. 2. Options B, C and D are correct Intramolecular hydrogen bond: increase the acidity. Ex: ortho Nitro phenol is more acidic than para Nitro phenol, Hydrogen bonding stabilize the anion after proton loosing. -I groups (NO2, CHO, CN etc) increases the acidity Conjugation of group also increases the acidity by resonance Ex: phenol is more acidic than methanol since phenoxide is stabilized by resonance which is not possible to methoxide. .

Which complex in the electron transport chain does not contribute to the proton gradient? Why not? Solution Ans - An electron transport chain ( ETC ) is a series of complexes that transfer electrons from electron donors to electron acceptors via redox (both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer of protons (H + ions) across a membrane. This creates an electrochemical proton gradient that drives the synthesis of adenosine triphosphate (ATP), a molecule that stores energy chemically in the form of highly strained bonds. The molecules of the chain include peptides, enzymes (which are proteins or protein complexes), and others. The final acceptor of electrons in the electron transport chain during aerobic respiration is molecular oxygen although a variety of acceptors other than oxygen such as sulfate exist in anaerobic respiration. The four complexes involved in electron transport chain are Complex II does not contribute to proton gradient in electron transport chain. This complex oxidizes succinate, which is produced in TCA cycle, and transfers electrons to ubiquinone. This complex is not associated with any proton gradient. .

where heat is transfer high in conduction or convection where heat is transfer high in conduction or convection Solution CONDUCTION-- Conduction is the transfer of heat between substances that are in direct contact with each other. The better the conductor, the more rapidly heat will be transferred. Metal is a good conduction of heat. Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them. This then continues and passes the energy from the hot end down to the colder end of the substance. CONVECTION-- Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continous circulation pattern. Water boiling in a pan is a good example of these convection currents. Another good example of convection is in the atmosphere. The earth\'s surface is warmed by the sun, the warm air rises and cool air moves in. Hence more heat is transferred by CONDUCTION because of the direct contact. .

Where do most college students exist on Maslow\'s hierarchy of needs? Be descriptive in your explanation of why... Please be orginial no articles or cut and paste what are your real thoughts! Thanks !! Solution I think that most college students exist between the Love and Belong and Esteem parts of the hierarchy on the pyramid. Many College students have achieved a sense of love and belonging through relationships wthi their friends and family.Â Â Students have made social connections by being members of sports teams, clubs, fraternities, sororities and other types of activities that help to achieve this pyramid level. At the same time, the need for belonging may become overcome other needs depending on the level of peer pressure. Also, college students have a need to feel respected and values by others. This spills into the Esteem layer of Maslow\'s hierarchy pyramid. Students will participate in a hobby, team or other organization to gain recognition of others. By doing this, students achieve a sense of value and acceptance from others. In some cases, there will be a need to achieve popularity or fame but this will not assist in achieving actual happiness as the sense of value and acceptance must really come from within the student .

The reported profit is proportional to the size of the equity investment. This is the standard technique used when one company has significant influence over another. When a company holds approximately 20-25% or more of another company\'s stock, it is considered to have significant control, which signifies the power that a company can exert over another company. This power includes representation on the board of directors, partaking in company policy development and the interchanging of managerial personnel. If a firm owns 25% of a company with a $1 million net income, that firm would report earnings of $250,000. When the equity method is used to account for ownership in a company, the investor records the initial investment in the stock at cost, and then that value is periodically adjusted to reflect the changes in value due to the investor\'s share in the company\'s income or losses. .

When the following equation is balanced properly under acidic conditions, what are the coefficients of the species shown? Fe2+ + PbO2 Fe3+ + Pb2+ Water appears in the balanced equation as a (reactant, product, neither) ? with a coefficient of . (Enter 0 for neither.) ? How many electrons are transferred in this reaction? Solution Balancing of redox equation--- --> break into two half-cell-- O: Fe2+ --> Fe3+ R: PbO2 --> Pb2+ --> Balance atoms other than O and H. Here already balance. --> Balance O with water and then water with H+-- O: Fe2+ --> Fe3+ R: PbO2 + 4H+ --> Pb2+ + 2H2O --> Now, Balance charge by e- -- O: Fe2+ --> Fe3+ + e- R: PbO2 + 4H+ + 2e- --> Pb2+ + 2H2O --> multiply first equation by 2 and then addup--- 2Fe 2+ + PbO 2 + 4H + ? 2Fe 3+ + Pb 2+ + 2H 2 O --> water appears as a product here with coefficient 2. --> 2 electrons are transferred in the reaction. if you have any query comment. if satisfied please rate it.. thanks.. .
