What happens when magnesium reacts with hydrochloric acid?

[LogicalAcid]

The acid: Hydrochloric
What happens step by step? I am unfamiliar with acids and bases, so I just want to know what's happening to help figure out. Thanks.

Magnesium is fairly reducing and so, depending on conditions (condentration, temperature) the acid would be reduced to form dihydrogen.

Mg --> Mg2+ + 2 e- E = 2.37 V
2H+ + 2e- --> H2 E = 0.0 V
