1. 4NH3 + 5O2 --> 4NO + 6H2O If you start with 80.0 g of O2 and 70.0 g of NH3, how many grams of NO will you produce?
2. Fe3O4 + 4CO --> 3Fe + 4CO2 100.0 g CO reacted with excess Fe3O4. If only 141.3 grams of Fe were produced, what was the percent yield?
3. 6PbO + O2 --> 2Pb3O4
How many moles of Pb3O4 will be formed from 334.8 g of PbO and 12.00 g of O2?
4. C5H12 + 8O2 --> 5CO2 + 6H2O
You start with 150.0 g of pentane and 500.0 L of O2. How many grams of H2O will you make?
