Answer

The balanced chemical equation are : $MgCO_3(s)+heat \rightarrow MgO(s)+CO_2(g)$ $Mg(OH)_2(s)+heat \rightarrow MgO(s)+H_2O(g)$

Work Step by Step

Calcination is the process of heating the mineral at a high temperature to remove impurities. Calcination of magnesium ores gives magnesium oxide and other products. The balanced chemical equations are : $MgCO_3(s)+heat \rightarrow MgO(s)+CO_2(g)$ $Mg(OH)2(s)+heat \rightarrow MgO(s)+H_2O(g)$
