That makes complete sense, I thought it was:
Quote
Mg(OH)2 + H2O ->
Magnesium hydroxide breaks down into: Mg(OH)₂(s) ⇌ Mg²⁺(aq) + 2OH⁻(aq) ... When coupled with water, the Mg²⁺ reactions with the oxygen of water, forming MgO and a water molecule
Sorry I just have another question regarding this topic, but for this specific question, I get how the equation is formed, but how would it look like coupled with water, like what did you do for it to become MgO if that makes sense, just want to be able to understand it better.

Hi Emily

Ok... Mg(OH)_2 breaks down into Mg2+ and 2 OH's. What happens then is Mg2+ is attracted to one of the oxygens, forming MgO, then you're left with 1 oxygen and 2 hydrogens, these form water.
