EXERCISE 2.2 CHEMISTRY FOR ENGINEERS

ELECTROCHEMISTRY

Practice Exercise 7. Calculate the cell potential for a galvanic cell in which the following reactions take place:

             2Al   +   3Pb2+ (0.1M)  ®  2Al3+ (0.01M)  +   3Pb




Practice Exercise 8.  A galvanic cell is constructed from a silver half-cell and a copper half-cell. The copper half-cell contains 0.10M Cu(NO3)2 and the concentration of silver ions in the other half-cell is unknown. If the silver electrode is the cathode and the cell emf is measured and found to be 0.10 v at 25oC, what is the Ag+ ion concentration?

Welcome to the answer sheet for Experiment 2.1: Calorimetry: Heat Capacity  Question 1. A 30g metal cube is heated to a temperature of 100.0 C and placed in a coffee-cup calorimeter containing 50.0 g water at 24.7C. The coffee-cup calorimeter is a non-ideal calorimeter. -q metal = water + qcalorimeter. Which of the following statements are true? Select all that apply. Answers: ONLY Select These Two Heat is Lost by the hot metal The calorimetry constant is greater than zero FORMULAS TO REMEMBER Remember: It is an easy process to remember. Just slowly do the steps in finding the Heat Capacity. Use other resources if you need more help!
