How many type of products are obtained on thermal decomposition of alkaline earth metal nitrates.

Correct answer

3

Step-by-step solution

All alkaline earth metal nitrates decompose to form metal oxide, NO2\text{N}{\text{O}}_{2} and O2.{O}_{2} .
So, three type of product:
2M(NO3)2→2MO+2NO2+O2(M=Be,Mg,Ca,Sr,Ba)\text{2}\text{M}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}} \to \text{2}\text{MO} + \text{2}{\text{NO}}_{\text{2}} + {\text{O}}_{\text{2}} \text{(M} = \text{Be,}\text{Mg}, \text{Ca}, \text{Sr,}\text{Ba)}
