AP Problem Set Chapter 3 Stoichiometry

Pace yourself so you can complete all the following before the test date.
If a formula is given, copy the formula. Show all calculations. If you write down a number, there is a unit beside it!! You must show work to justify your answer.

Pages 117-119 #’s 27, 30, 34, 38, 51, 53, 57, 60, 62
Pages 119-120 #’s 65, 66, 68, 70, 71, 73, 77

Write down all equations. Leave space in front of each reactant and product to add coefficients if needed. Leave 1 line between each equation on your paper.

Pages 120 – 121 #’s 81-88

Write a balanced chemical equation. Leave room around your equation to label the amounts of reactants and products. Show all calculations. If you write down a number, there is a unit beside it!! You must show work to justify your answer.
