# How do we use the method of half-equations, and redox formalism to represent the oxidation of magnesium metal by hydrochloric acid?

##### 1 Answer

The

#### Explanation:

You have performed a redox reaction, the which we could formally separate into oxidation/reduction half equations.......

And a reduction half-equation.......

A oxidizing protium ion formally gains one electron........

We add

........alternatively.......

Charge and mass are CONSERVED, as is absolutely required for ANY chemical reaction.......
