1. (a) Create the target equation that represents the combustion of magnesium. Mg + O₂ MgO (Is this equation correct?)

(b) Consider the follow three equations:

Reaction 1: Mg_(s) + 2HCl_(aq) H_2(g) + MgCl_2(aq) H = ?

Reaction 2: MgO_(s) + 2HCl_(aq) H₂O_(l) + MgCl_2(aq) H = ?

Reaction 3: O_2(g) + H_2(g) H₂O_(l) H = ?

(c) Describe what must be done to reactions 1-3 at the target equation. (Please give a simple explanation).

Thank you.
