- DNone
✓
Answer
Correct option: A.
heating of $NH_4NO_3$
a
Reactions are:
Reactions are:
$NH _4 NO _3 \rightarrow N _2 O + H _2 O$
$NH _4 NO _2 \rightarrow N _2+ H _2 O$
$NH _4 Cl _{\rightarrow} NH _3+ HCl$
$NH _4 NO _3(a q)+ NaOH (s) \rightarrow NH _3(g)+ H _2 O (l)+ NaNO _3(a q)$
$CaCN _2+3 H _2 O \rightarrow CaCO _3+ NH _3$
