Question

Thermal decomposition of ammonium dichromate gives

$N_2, H_2O$ and $Cr_2O_3$

$N_2 NH_3$ and $CrO$

$(NH_4)_2CrO_4$ and $H_2O$

$N_2, H_2O$ and $CrO_3$

Answer

$N_2, H_2O$ and $Cr_2O_3$

Explanation

Solution

Thermal decomposition of ammonium dichromate $\left( NH _{4}\right)_{2} Cr _{2} O _{7}$ on heating gives $N _{2}, Cr _{2} O _{3}$ and $H _{2} O$ as follows: $\left( NH _{4}\right)_{2} Cr _{2} O _{7} \stackrel{\Delta}{\longrightarrow} N _{2}+ Cr _{2} O _{3}+4 H _{2} O$
