• A. $N{H}_{4}Cl\left(aq\right)+NaN{O}_2\left(aq\right)\to$
• B. $(N{H}_4{)}_{2}C{r}_2{O}_7\stackrel{\Delta }{\to }$
• C. $Ba(N_3{)}_2\stackrel{\Delta }{\to }$
• D. $N{H}_{2}CON{H}_2+H_{2}O\to$

Answer 1

The correct option is D $N{H}_{2}CON{H}_2+H_{2}O\to$

(a) $N{H}_{4}Cl\left(aq\right)+NaN{O}_2\left(aq\right)\to N_2\left(g\right)+2H_{2}O\left(l\right)+NaCl\left(aq\right)$
(b) $\left(N{H}_4{)}_{2}C{r}_2{O}_7\stackrel{\Delta }{\to }{N}_2\right(g)+4H_{2}O(l)+C{r}_2{O}_3(s)$
(c) $Ba\left(N_3{)}_2\stackrel{\Delta }{\to }Ba\right(s)+3N_2(g)$
(d)$N{H}_{2}CON{H}_2+2H_{2}O\to (N{H}_4{)}_{2}C{O}_3\rightleftharpoons 2N{H}_3(g)+H_{2}O(l)+C{O}_2(g)$
