MAP LEVEL:
1. Does the atomic mass given on the periodic chart take into account all of the naturally occurring isotopes?
2. What is the advantage to chemists of using the mole?
3. Can the formula of a compound be determined by chemical analysis and how?
4. Balanced equations provide a recipe for a reaction. Can these balanced equations be used to determine measurable amounts of reactants and products in the lab?
5. How can limiting reagents be used to determine the theoretical yield of product.
6. Can the percent yield of product be determined from laboratory data?
