Iron reacts with superheated steam(H2O) to form hydrogen gas and the oxide Fe2O3. (write) Balance this chemical reaction. And if 10grams of Iron react with excess steam, how many grams of Fe2O3 are produced? How many grams of H gas? How many grams of H2O consumed???
Here is the balanced equation.
4Fe + 6H2O ==> 6H2 + 2Fe2O3
Here is a link to a worked example of a stoichiometry problem. Just follow the steps to work any stoichiometry problem.
