Question

What are the products formed, when $\left(A\right)N{H}_{4}V{O}_3$ is heated and when $\left(B\right)(N{H}_4{)}_{2}C{r}_2{O}_7$ is heated.

• A. in both cases $N_2$ is formed
• B. in both cases $N{H}_3$ is formed
• C. in (A) $N{H}_3$ and in $\left(B\right)N_2$ are formed
• D. in (A) $N_2$ and in $\left(B\right)N{H}_3$ are formed

Answer 1

The correct option is C in (A) $N{H}_3$ and in $\left(B\right)N_2$ are formed

$\left(A\right)N{H}_{4}V{O}_3$ on heating forms $N{H}_3$
$\left(A\right)N{H}_{4}V{O}_3\stackrel{heat}{\to }N{H}_3+HV{O}_3$
$\left(B\right)(N{H}_4{)}_{2}C{r}_2{O}_7$ on heating forms $N_2$
$\left(B\right)(N{H}_4{)}_{2}C{r}_2{O}_7\stackrel{heat}{\to }{N}_2+\underset{green}{C{r}_2{O}_3}+4H_{2}O$
