Solution

$C a (N O_{3})_{2}$ decomposes into gases $N O_{2}$ and $O_{2}$ .
$2 C a (N O_{3})_{2} ⟶ 2 C a O + 4 N O_{2} + O_{2}$
All the nitrates of alkaline earth metals undergo thermal decomposition to give the metal oxide, nitrogen dioxide and oxygen. The nitrates are white solids and the oxides produced are also white solids. Brown nitrogen dioxide gas is given off together with oxygen.
