1. For the balanced equation shown below, if 40.2 grams of Fe were reacted with 9.81 grams of H2O, how many grams of H2 would be produced?
3Fe+4H2O=>Fe3O4+4H2
2. For the balanced equation shown below, if 1.75 grams of P4 were reacted with 1.68 grams of O2, how many grams of P4O10 would be produced?
P4+5O2=>P4O10
3.
4. For the balanced equation shown below, if 29.3grams of Ba were reacted with 4.98 moles of 02, how many grams of BaO would be produced?
2Ba+O2=> 2BaO
5. For the balanced equation shown below, if 42.1 grams of ZnS were reacted with 10.9 grams of O2, how many grams of SO2 would be produced?
2ZnS+3O2=>2ZnO+2SO2
CBr4+O2=>CO2+2Br2
2Fe+3Cl2=>2FeCl3
2Al+Cr2O3=>Al2O3+2Cr
CH2S+3O2=>CO2+H2O+SO3
CH3COF+H2O=>CH3COOH+HF
