<b>From previous objective, not gotten to on last test. Now on this test.

3. Understand the difference between an Empirical Formula (EF) and Molecular Formula (MF) and how it relates to the subscripts of the chemical formula.

4. Calculate EFand MF. This include determining EF from mass data, percent composition info, and MF from mass data, percent composition and EF data.

5. Predicting Products of:

6. Explain the difference between a complete chemical reaction and a net ionic reaction


Updated 2006 - (5.6) Calculate percent yield in a chemical reaction (also in Limiting Reactant & Redox section)
