Stoichiometry Movie Quiz Foothill Chemistry

1. What is the base unit for mass in the metric system? Gram Kilogram Liter Decigram

2. You can NEVER change the ______ when balancing a chemical equation Coefficients Reaction Rate Subscripts Bond Length

3. What is the molar mass of H2O? 18.02 g/mol 17.01 g/mol 33.01 g/mol 32.01 g/mol

4. When computing an empirical formula, your ratio of elements are as follows: 2 N : 1.5 O: 6 H. What is the empirical formula? It’s not multiple choice. You just have to answer.

5. The empirical formula for a compound is H6O3N, the molar mass is 272.20 g/mol. What is the chemical formula? Not multiple choice, you just have to answer

6. If the theoretical yield of a reaction is 75. 0 g, and 50 6. If the theoretical yield of a reaction is 75.0 g, and 50.0 g are produced, what is the percent yield? Again not multiple choice.
