1. The problem statement, all variables and given/known data
When acid and metal oxide react the product is salt and water.

2. Relevant equations
Write the reaction formula, when hydrochloric acid reacts with magnesium oxide

3. The attempt at a solution
Hcl and MgO
2 Hcl + MgO ------> 2H2O+ MgCl
I still find it not balanced and dunno how balance it

How do you balance reaction equations in general?

It's [itex] MgCl_2 [/itex]

Magnesium oxide reaction

Advice: before wondering how the atoms in a reaction can be balanced, you need to write all the formulas correctly.

Magnesium is divalent (you can see that in the monoxide, it has the same valence as the oxygen, 2) and this is a simple reaction, it will not get reduced, so in the salt it must have the same valence, namely 2.

That's more like it.
