Sheet No 2: Stoichiometry
1- How many grams of CO2 are produced if 2.09 mol of HCl are reacted according
to this balanced chemical equation?
CaCO3 + HCl CaCl2 + CO2 + H2O
2- How many
At the beginning of Chapter 8, a comparison was made between solving
stoichiometry problems and making turkey sandwiches. Look at the
sandwich recipe once more.
2 bread slices ! 2 turkey slices ! 1 lettuce le
Stoichiometry Set 2 Limiting Reactants
1. Heating zinc sulfide in the presence of oxygen yields the following:
ZnS + O2 ZnO + SO2
If 1.72 mol of ZnS is heated in the presence of 3.04 mol of O2, which reactant will be used up? Balance
the equation first.
