I. H low do you know when to name something as an ionic compound? 2. How do you know when to name something as a molecular compound? 3. How does nami ing an ionic compound differ from naming a molecular compound? 4. How do you know when a polyatomic ion is present? 5. Why do we include a Roman numeral in the name for compounds containing a transition metal and not for main group metals? Solution 1. When we see that a metal (cation) is bonded to a non-metal (anion) we detect it to an ionic compound and name it so. 2. When two elements of comparable electronegativity combine to form a molecule it then becomes a covalent compound. 3. In naming ionic compounds we generally name the cation and anion separately. Molecular compounds either have trivial names or are named according to IUPAC rules. 4. Polyatomic ions are placed in brackets and so we can detect them. 5. Transition metals can have more than one oxidation states which normal metals dont. So, the roman numerals are included to indicate oxidation states of the transition metals. .

I. Describe the different bonds that exist between the different macromolecules (Big 4). If there are variations in bonding that change physical properties make sure to mention that as well. Solution Hi, Among the big 4, 1. Carbohydrates have glycosidic linkages (C-O-C bond) between monosaccharides which form a dehydrated polysaccharide. Larger number of glycosidic linkage leads to a decrease in solubility of saccharide in water. 2. Proteins have peptide bonds which are formed via dehydration between amino acid chains (COOH and NH2 group form CO-NH). These bonds help amino acid units to form large structures (sheet/helix) of proteins. The presence of these bonds help in stability of proteins. 3. Lipids have mostly non-bonded interactions (and hydrogen bonds at polar head of the lipid) the interactions/H-bonds interplay in self aggregation and micellization of lipids. 4. Nucleic acids are composed of 5 carbon sugars mostly, with phosphate group attached to a CH2 group as C-O-P bond. The two COP bonds help forming long chain structures like DNA, apart from COP, C-N bond is also formed between nucleic acid and nitrogenous bases (A,T,U,G,C). Thanks, .

I) What are secondary bonding interactions (also called charge transfer interactions) and which elements are they most relevant to? II) Which halogen can be used to support central atoms in their highest oxidation states? Solution I)In a complex if one component is a good electron donor and the other a good electron acceptor, charge transfer interactions may occur. Several trasition metal complexes show charge transfer interactions. Electrons migrate from orbitals which has predominantly ligand character to orbitals having predominantly metal character or vice versa depending on energy of the orbitals.These can be identified by high intensity bands in their electromagnetic spectra. II)Among halogens Iodine is a good candidate as it is a good donor as well as a good acceptor. For metals in high oxidation state electron density can be transferred from iodine to metal centre more effectively (due to low electron affinity and high polarisability).This stabilizes the complex. .

The only intermolecular forces in methane are London dispersion forces.The major intermolecular forces would be dipole-dipole forces and London dispersion forces. But The electronegativities of C and H are so close that C-H bonds are nonpolar. There are no bond dipoles and no dipole-dipole interactions.Even if the molecule had polar C-H bonds, the symmetry of molecule would cause the bond dipoles to cancel.So the only forces left to consider are London dispersion forces. .

I need help writing a python 3 function. I need to write a function that takes 3 inputs which are lists (first names, middle ini., and last names ). It needs to take those names and put them together correctly and then print them in a column, 1 on top of another, and so on. they need to be printed in aphabetical order of the last names. Also, they need to have a border around the whole column and the initials need to be aligned vertically. if there is no initial, a space can just take its place to keep things aligned. I feel like being able to look at the code and go over it line by line until I understand it and can recreate it myself is the best way I learn. If someone could create this function for me, that would be unbelievably helpful. Thanks SO much for the help and sorry for any grammar issues, I\'m writing this from my phone Solution def createNames(firstName, middleName, lastName): #creating a function to generate names from the given lists and give output of names in a list allNames=[] for i in range(len(firstName)): name=lastName[i]+\" \"+middleName[i]+\" \"+firstName[i] allNames.append(name) allNames.sort() Â Â #sorting the names in alphabatical order of lastNames return allNames firstNames=[] Â Â #give here firstNames middleNames=[]Â Â #give here middleNames lastNames=[]Â Â #give here lastNames namesList = createNames(firstNames, middleNames, lastNames) print(\"_______________________________\ \") for name in namesList: print(name+\"\ \")Â Â #printing the names one by one print(\"_______________________________\") .

I need help with my geotechnical engineering HW,, Can a soil have a low void ratio and a low total unit weight at the same time? Explain. Name and define three types of weathering. From memory, try to write the equations for water content, void ratio, dry unit weight, moist (total) unit weight, and saturated unit weight. After 5 minutes you can look up the definitions, and write the correct answers below your attempt. For a given soil, the following parameters are known: e -0.62, specific gravity 2.65, moisture content w=15% Determine: 3. 4. 5. 6. dry unit weight moist unit weight water content at S-100% saturated unit weight . Solution 3. No, low void ratio and low total unit weight at the same time are possible, beacause if void ratio is low ultimately the mass of the solids is high so that the unit weight increases. 4.Types of Weathering: i) Mechanical weathering: which produces clasts of rock/mineral which are smaller that the original and of the same general composition. There are two basic processes: Fracturing and Abrasion ii) Chemical weathering: It also produces smaller pieces, but of a different chemical composition, the minerals have been changed in an attempt to be more in balance with surface conditions. iii) Biological weathering: It is the action of plants and animals can and do lead to both mechanical and biological weathering. 5. Water Content = Weight of water/weight of solids Void ratio = volume of voids/volume of solids Moist unit weight = mass of soil * accleration due to gravity / volume of soil Dry unit weight = mass of solid * accleration due to gravity / volume of soil or moist unit wieght/(1+water content) Saturated unit weight = submerged unit wiegt + unit weight of water 6. Dry unit Weight = 16.35 KN/cubic meter Moist unit Weight = 18.81 KN/cubic meter Water content at S=100%, w=23.39% Saturated Unit Weight = 20.185 KN/cubic meter .

12. Your friend has high protein and sugar in her urine. She repeats the tests and determines that these components are repeatable, suggesting they are present in her urine. What does this signify to you, as her friend and primary care physician? Solution Everyone has protein in their blood. The main protein in your blood is called albumin. healthy kidneys should only filter tiny (trace) amounts into the urine as most protein molecules are too large for the filters (glomeruli). When she have protein in her urine, it is called proteinuria (or albuminuria), which is usually a sign of chronic kidney disease. As proteinuria progresses, oedema may occur. High levels of glucose in her urine may indicate hyperglycemia, or high blood sugar, which often indicates the onset of diabetes. Untreated hyperglycemia can lead to ketoacidosis, which can result in diabetic coma and even death. Possible causes of proteinuria: 1. Diseases of the glomeruli like glomerulonephritis or diabetes. 2. Urine infection such as cystitis/urinary tract infections. 3. Congestive heart failure, a first warning of eclampsia in pregnancy. 4. May be she tested concentrated urine samples (early morning), or if she have become dehydrated or havenâ€™t drunk much. It is also better to check protein/creatinine ratio (PCR test). 5. Temporary proteinuria may occur after vigorous exercise or if she have a high fever. Hope this helped you! Thank You So Much! Please Rate this answer as you wish.(\"Thumbs Up\") .

11. What are the components of the user interface? Solution Now a days there are lots of types of user interfaces. We are going to describe the components in general, using four main categories: Containers: This are panes, windows, forms which hold other components. Containers have grids in order to arrange other components. There are rows and columns grids, flexible grids, flow grids. Containers also has the responsibility to adapt to the screen size. Some containers are: Window Frame Form Dialog Menus: This user interface components allows the user to navigate through the different commands of a given applications. Menus organize commands in a logical and hierarchical manner, using several submenus. Some types of menu are: Main Manu (located on the top of the container). Menu Bar Contextual Menu Controls. This components allows communication between the user and the application. This allows the user to send and receive request, messages and information from/to the application. This the category which hold the bigger number of components. Some of them are the following: Text Boxes Text Area Buttons File Control Select List Check Optinon Label Tables Graphic Area Media Controllers: The controller is not a graphic component but it is necessary to process input/output. This are pieces of code which capture user interaction, takes arguments and details and finally process commands and requests. Normally the controller uses the publisher/subscriber pattern. It subscribes itself with the components and receive notifications when the events occur, being able to react accordingly. .
