How could magnesium oxide become contaminated with magnesium carbonate? and what would happen if you added hydrochloric acid to this contaminated sample?

If the magnsium oxide became wet, then it would form magnesium hydroxide, which could absorb carbon dioxide from the air to form a bit of magesium carbonate.
If HCl was added to pure MgO, the solid would just dissolve, but if there was any magnesium carbonate present, you would see fizzing as well.

MgO has a molecular bond, so it doesn't have a numerical prefix. For now, imagine of it as even with the truth that any compound with a metallic in it truly is going to be molecular, and subsequently no longer want a prefix.

Can absorb CO2 from the air. Acis wioll liberate CO2 and cause a fizz
