1. In the Iron and Copper (II) chloride lab, if in massing out the product, you wrote down a mass that was greater than the actual mass of copper produced, how would the value of the percent yield of copper be affected? Explain.
2. In the Rate of Reaction Lab (I called it the Clock lab), what physical observation did you use to determine the rate of the reaction? What chemical(s) caused this physical observation?
3a. In Part II of the Le Chatelier's Principle Lab, what was the physical observation that you used to determine that the equilibrium had shifted? ___________________
3b. If I had added in NaCl instead of NaOH into a test tube with CrO42-, what would you observe and explain why it occurred?
4. In the Synthesis part of the Types of Chemical Reaction lab, the two products you (and their physical observation was:
a Observation of Product 1: ________________________
Chemical Formula and Name of Product 1: _______________________
b. Observation of Product 2: ________________________
Chemical Formula and Name of Product 2: _______________________
