• A. True
• B. False

Answer 1

The correct option is A True

Nitrogen can be obtained by Thermal decomposition of ammonium dichromate.

The volcano demonstration involves igniting a pile of the salt, which initiates the following exothermic conversion:

$\left(N{H}_4{)}_{2}C{r}_2{O}_7\right(s)\to C{r}_2{O}_3(s)+N_2(g)+4H_{2}O$ (g) (H=429.1 3 kcal/mol)
