The reduction of iron (III) oxide creates the following reaction:
Fe2O3 (s) + 3 H2 (g) → 2 Fe (s) + 3 H2O (g)
If the above reaction only went to 75% completion, how many moles of Fe2O3 were require to produce 0.850 moles of Fe?
Ammonia, NH3, can be created from the combining of H2 and N2 molecules. How many grams of ammonia are isolated when 10.0 g H2 reacts with excess N2 with a chemical reaction that has a 79.3% yield?
3 H2 + N2 → 2 NH3
34.4 g
53.0 g
44.7 g
14.5 g
