Oxidation-Reduction Activity Series Peter Jeschofnig, Ph.D. Version 42-0186-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Data Table: Oxidation-Reduction Reactions Mg in Na2SO4 → Bubbles for a few seconds Zn in MgSO4 → Small bubbles formed on Zinc Pb in Zn(NO3)2 → Changed color of Lead into a darker color Pb in FeCl3 → A slight yellow formed on Lead Fe in CuSO4 → Changed the Iron into a different color, Red-Orange Questions A. Based on your observations make an activity series of the metals used. List them in such a way that the most active metal is on the left and the least active metal is on the right. Remember, sodium and copper are metals, too. B. Suppose you inserted a piece of copper into a solution of nickel chloride and observed no reaction. Then if you inserted a piece of iron into the solution of nickel chloride a nickel deposit formed on the bottom of the well in the well plate. Where does nickel fit into your activity series? The chemical reactions for the preceding question B are: Cu (s) + NiCl2 (aq) à no reaction Fe (s) + NiCl2 (aq) à 2 Ni (s) + Fe Cl2 (aq) Ans) The nickel chloride would fit in between aluminum and Iron. The nickel chloride must be more active than copper. Otherwise the copper would replace the nickel in a reaction C. Suppose you inserted a piece of an unknown metal into a solution of zinc (II) nitrate and observed no reaction. Then if you inserted the unknown piece of the metal into the solution of iron (III) chloride a deposit formed on the bottom of the well in the well plate. Where does the unknown metal fit into your activity series? Ans) it should go between Iron and Copper because is more reactant than magnesium For the reaction (Fe (s) + NiCl2 (aq) à 2 Ni (s) + Fe Cl2 (aq) identify: 1. The oxidation number of Ni (s) = 0 2. The oxidation number of Fe in the FeCl2 (aq) = +2 3. The oxidation number of Cl in the FeCl2 (aq) = -1 4. The oxidation number of Fe (s)= 0 5. The oxidation number of Ni in the NiCl2 (aq) = +2 6.

?? NaCIO, Bu4NHSO4 EtOAc (ethyl acetate) Benzophenone Benzhydrol Solution A phase-transfer catalyst enables the reaction in a heterogeneous system between general organic compounds soluble in organic solvents and compounds soluble in water such as inorganic salts. The reaction can be accomplished in a biphasic system of an inexpensive nonpolar aprotic solvent and water without using DMSO or DMF which are high-polar solvents. A phase-transfer catalyst is soluble in both solvents, and it carries anions of inorganic salts into organic solvents and returns them into the water phase. Reactions usually progress under mild conditions with easy work-up procedures. For this reason, they are also used industrially. Typical phase-transfer catalysts are quaternary ammonium salts, crown ethers, and phosphonium compounds etc. Phase-transfer catalysis (PTC) has been widely used for the synthesis of organic compounds for more than three decades. Phase transfer catalysis (PTC) uses catalytic amounts of phase transfer agents which facilitate the interphase transfer of species, making reactions between reagents in two immiscible phases possible. PTC is used widely in the synthesis of various organic chemicals in both liquid-liquid and solid-liquid systems. .

(Multiple choice) Which one of the following statements is true? Explain why they are T/F. (a) In metals, dislocations provide easy pathways for conducting electrons. (b) When a hole is created by thermal excitation of an electron across the band gap (1.1 eV) in silicon (atomic number 14), it has the same charge as a hole created by thermal excitation of an electron across the band gap (0.67 eV) in germanium (atomic number 32). (c) When a reverse-bias potential is applied across a p-n junction in doped Si, the flow of charge carrier across the junction will be insignificantly small. (d) In any given intrinsic semiconductor, the mobility of holes in the conduction band is lower than the mobility of electrons in the conduction band. (e) The addition of Ge to Si produces an extrinsic semiconductor. Solution (d) is correct . qE= E-Eg (in eV) so, lesser Eg gives more charge. (e) is false because Ge (+4 valency) will retain nature of doping in Si. (c) it would be significantly small i.e.,much lesser. .

- What is continuous linked settlement and how does it operate? - What is a quotation and how does it work in cross currency? Solution What is continuous linked settlement and how does it operate? Continuous Linked Settlement Continuous Linked Settlement is a process by which a number of the world\'s largest banks manage settlement of foreign exchange amongst themselves, their customers and other third-parties. It is an industry initiative to eliminate the settlement risk in foreign exchange transactions. This is achieved by using a \'payment versus payment\' method, which provides a simultaneous exchange of currency values through Continuous Linked Settlement Bank International (CLS) How is CLS managed? Settlement Members have direct links to CLS to input deals on their own and their customers\' behalf. They effect settlement on the due dates through accounts held at the CLS Bank. User Members have the same direct access, but use a Settlement Member to handle their settlement on the due dates. Third Parties have no direct links to CLS, and their trades must be sent to CLS via a Settlement or User Member. Most banks (as well as major corporates with their own FX departments), that wish to use CLS, do so as Third Parties) How does Continuous Linked Settlement work? When a foreign exchange deal is struck between banks, each counterparty transmits the details to CLS Bank, where they are matched and held until the settlement date. At the start of day, each Settlement Member .

. What is a right-to-work state? What are the advantages or disadvantages of doing business in a right-to-work state? Solution A Right to Work law secures the right of employees to decide for themselves whether or not to join or financially support a union. However, employees who work in the railway or airline industries are not protected by a Right to Work law, and employees who work on a federal enclave may not be. Moreover, a Right to Work law does not prohibit limitations on when a dues deduction authorization card can be revoked. The Advantages of the Right to Work Right-to-work laws prevent union organizations from monopolizing work opportunities. An outgrowth of the Taft-Hartley Act of 1947, right-to-work laws prohibit employers from creating exclusive relationships with labor unions. Right-to-work laws guarantee that nonunion employers and nonunion workers can bid on jobs that would otherwise be restricted for union labor The Disadvantages of Right to Work States Right-to-work states prohibit unions and employers from forcing employees to join a union or pay union dues as a condition of employment. These states also prevent denial of employment to non-union members or requiring a fee for the right to work. Nearly half of all states are \"right-to-work\" states. Advocates of right-to-work laws claim stronger economic growth indicators, such as lower unemployment rates, interstate migration and higher gross domestic product (GDP) growth. However, right-to-work can potentially weaken collective bargaining, inhibit worker wage growth and allow for employee termination without just cause .

(b) Ionization energy generally increases from left to right across the second period element, but boron, which is to the right of beryllium, has a lower ionization energy than beryllium. Explain. Bor on has a lower Ionization energy Beryllium than be cause He D Ã˜shell only contains one ele ce von which makes it less stable the Beryllium which has a tulis oy bital. Muh s Solution Generally in the periods from left to right Ionisation Energy increases... Because decrease in atomic radii. But Boron having less Ionisation Energy compare to Beryllium it\'s neighbour element, reason: BORON electronic configuration 1s2 2s2 2p1 Beryllium electronic configuration 1s2 2s2 Beryllium contains completely filled 2s orbital, so it gives extra stability. That is why it needs more energy to remove the electron. Where as Boron has 2p1 electron in its valence shell it can be easily removed, so it has low Ionisation Energy .

- How are corporate hierarchies related to the systems concept? Solution The concept of corporate hierarchies and the concept of systems is simpilar to eachother. The arrangement of individuals within a corporation according to power, status and job function. In a public company, usually the board of directors will be at the top, followed by the CEO, who may also be the chairman of the board of directors as well as the president. Below the CEO will be other C-level executives, such as the CFO, CIO and COO, followed by upper management (vice-presidents/managers/directors), then the employees in each department who are further broken down into levels of experience and authority. Similarly, A system is a set of interacting or interdependent component parts forming a complex/intricate whole. [1] Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning. The term system may also refer to a set of rules that governs structure or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure or behavior. .
