Iron (III) Oxide, FE2 O3, reacts with hydrogen gas, H2, at elevated tempertures to produce iron metal and water. The unbalanced equation is:
FeO3(s) + H2(g) delta-> Fe(s) + H2O (g)
A) What mass of hydrogen gas, H2, must be consumed to produce 10.0 g or iron Metal?
Mass of H2= ______
B) What mass of Iron (III) oxide, Fe2, O3, must be consumed to prepare 2.50 g of iron metal?
Mass of Fe2O3=_____
Can you please help with this?
