The zinc within a copper-plated penny will dissolve in hydrochloricacid if the copper coating is filed down in several spots (so that thehydrochloric acid can get to the zinc). The reaction between theacid and the zinc is 2 H+(aq) + Zn(s) ¡ H2(g) + Zn2+(aq).When the zinc in a certain penny dissolves, the total volume of gascollected over water at 25°C is 0.951 L at a total pressure of748 mmHg.

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".
