Chlorine gas can be prepared in the laboratory by the reaction of hydrochloric acid with manganese (IV) oxide. 4HCl (aq) + MnO2 (s) ⟶MnCl2 (aq) + 2H2O (l) + Cl2 (g) A sample of 37.7 g MnO2 is added to a solution containing 46.3 g HCl.

Zn (s) + 2 HCl (aq) →ZnCl2 (aq) + H2 (g) Zn (s) reacts with HCl (aq) according to the equation shown above. In trial 1 of a kinetics experiment, a 5.0g piece of Zn (s) is added to 100mL of 0.10MHCl (aq).
