Thermite welding is an exothermic reaction, which produces molten iron that permanently binds metals as it cools. The process does not require heat or electricity. Aluminum powder is simply mixed with ferric oxide powder. The reaction is accompanied by a release of heat, and produces aluminum oxide and molten iron. If 55.0 grams of aluminum powder is mixed with 75.0 grams of ferric oxide, which of the two substances is the limiting reagent? The excess reagent? How many grams of molten iron will be produced?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
