Question

hydrochloric acid with magnesium oxide to yield manganese chloride plus water plus chlorine gas

Answer 1

What's the question?

The reaction as you have written it does not occur.

First, you can't make manganese chloride when you start with magnesium. So maybe you mean magnesium chloride instead of manganese chloride.

Second, the reaction as written, even if we say it yields magnesium chloride, doesn't happen because we don't make chlorine gas.

So, the reaction should read as follows:

hydrochloric acid with magnesium oxide to yield magnesium chloride and water

2HCl + MgO ==> MgCl2 + H2O ... balanced equation
