Vedclass · Answer

(A) Let us analyze the given reactions:$1. NH_4Cl(aq) + NaNO_2(aq) \longrightarrow N_2(g) + 2H_2O(l) + NaCl(aq)$. This reaction produces dinitrogen.$2. NH_2CONH_2 + 2H_2O$ $\longrightarrow (NH_4)_2CO_3$ $\longrightarrow 2NH_3 + H_2O + CO_2$. This reaction produces ammonia.$3. Ba(N_3)_2 \stackrel{\Delta}{\longrightarrow} Ba(s) + 3N_2(g)$. This reaction produces pure dinitrogen.$4. 2NH_4Cl + Ca(OH)_2 \longrightarrow CaCl_2 + 2H_2O + 2NH_3$. This reaction produces ammonia.Thus,reactions $1$ and $3$ produce dinitrogen.

List-$I$ Name of oxo acid	List-$II$ Oxidation state of $P$

$(b)$ Orthophosphoric acid	$(ii) +4$
$(c)$ Hypophosphoric acid	$(iii) +3$
$(d)$ Orthophosphorous acid	$(iv) +2$
	$(v) +1$

Which reaction$(s)$ among the following produce dinitrogen?
$1. NH_4Cl(aq) + NaNO_2(aq) \longrightarrow$
$2. NH_2CONH_2 + 2H_2O \longrightarrow$
$3. Ba(N_3)_2 \longrightarrow$
$4. NH_4Cl + Ca(OH)_2 \longrightarrow$
