Name: ______Period: ______Date: ______
1. Example: 2 AgNO3 + 1 Cu ->1 Cu(NO3)2 + 2 Ag
How many moles of Ag will be produced by the complete reaction of 1.76 g of Cu?
1.76 g Cu X 1 mol Cu X 2 mol Ag = 0.055 mole Ag
63.5 g Cu 1 mol Cu
2. 1 Fe2O3 + 3 CO -> 3 CO2 + 2 Fe
When 116 g of CO reacts with an excess of Fe2O3, how many moles of iron will be produced?
3. 2 Cl2 + 4 NaOH -> 3 NaCl + 1 NaClO2 + 2 H2O
What number of moles of Cl2 is needed to react with 14.4 g NaOH?
4. 3 Cl2 + 6 NaOH-> 5 NaCl + 1 NaClO3 + 3 H2O
What number of moles of chlorine molecules are needed to react with 10.9 g of NaOH?
5. 3 H2 + 1 N2 -> 2 NH3
What number of moles of ammonia can be produced from 8.0 g H2?
