The net ionic equation for the reaction of magnesium oxide (MgO) with the strong acid HCl is:2H₃O⁺(aq) + MgO(s) → 3H₂O(l) + Mg²⁺(aq)This equation shows that the reaction between magnesium oxide and hydrochloric acid produces water and magnesium ions. The chloride ions from the hydrochloric acid do not participate in the reaction, so they are not included in the net ionic equation.
