Aluminum and Hydrochloric acid react to form aluminum chloride and hydrogen gas

The balanced chemical equation for the reaction between aluminum and hydrochloric acid is:

2 Al + 6 HCl → 2 AlCl3 + 3 H2

In this reaction, two moles of aluminum combine with six moles of hydrochloric acid to produce two moles of aluminum chloride and three moles of hydrogen gas.
