Prelab Questions: (PL1) For 6 galvanic cell combinations in part 1, write a chemical equation for each cell in a direction that would be spontaneous and the overall cell potential (PL2) For part 2, what is the expected cell potential for that concentration cell? (PL3) Draw a data table you will be filling in during the lab. Include all the measurements that will be made in this lab and qualitative observation if needed. Procedure: Part 1) (1) Obtain copper strip,...

1) What can happen if peroxides are present in dicyclopentadiene? 2) What does cracking of dicyclopentadiene mean?
(a) Explain what would happen if the gate is made positive with respect to the cathode during reverse blocking of a thyristor (no diagram required) [15%] (b) Draw a well labelled plot showing the variation of the anode voltage versus anode current of a thyristor (no graph paper, explanation or circuit diagram needed) [20 %] (c) Consider the circuit diagram shown below. Here V is the DC source voltage and the initial charge of the capacitor C is q(0)-0 ....
Start by reading the statement, “Common disorders commonly occur and rare ones rarely happen.” 1. What would be the expected ratio of generalist to specialist physicians in the United States based on this statement? 2. What is the true ratio? What efforts have been made to manage the maldistribution of physicians?

Questions 1. Why is it necessary to write the balanced chemical equation for the reaction before completing any stoichiometry problems? The balanced equation makes it possible to Convert information about a reactant or product to quantitative data, per the Conservation of matter. 2. What does your percent yield indicate about the amount of copper actually formed in the reaction? Did you produce all the copper expected? Explain. 3. Based on your percent yield, indicate a source of error...
11) Explain what would happen to your ratio if the following happened: a) not all of the Ag+ ions reacted with the copper metal b) the silver was not completely dry c) you used a different balance for each massing __ mol Cu(s) + ___ mol AgNO3(aq) → ___ mol Ag(s) + ___ mol Cu(NO3)2(aq) My coefficients for this stuff was 1 2 2 1 .
