Question

solid magnesium carbonate reacts with an aqueous solution of perchloric acid. express your answer as a balanced chemical equation. identify all of the phases in your answer.

Explanation:

Step1: Write the reactants

Magnesium carbonate ($MgCO_3(s)$) and perchloric acid ($HClO_4(aq)$).

Step2: Determine the products

The reaction produces magnesium perchlorate ($Mg(ClO_4)_2(aq)$), water ($H_2O(l)$) and carbon - dioxide ($CO_2(g)$).

Step3: Balance the equation

The balanced chemical equation is $MgCO_3(s)+2HClO_4(aq)=Mg(ClO_4)_2(aq)+H_2O(l)+CO_2(g)$.

Answer:

$MgCO_3(s)+2HClO_4(aq)=Mg(ClO_4)_2(aq)+H_2O(l)+CO_2(g)$
