In the Haber Process, hydrogen (H2) and nitrogen (N2) react to produce ammonia (NH3)   H2 + 3H2 ----> 2NH3 This reaction releases heat. How does the reaction influence the mass of the reacting chemicals? a. Mass decreases because some mass is converted into heat energy. b. Mass increases because a more complex compound is produced. c. Mass stays the same because no matter is created or destroyed. d. Mass stays the same because molecular mass remains constant.

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".
