Answer 1

$(N{H}_4{)}_{2}C{r}_2{O}_7\stackrel{\Delta }{⟶}{N}_2+4H_{2}O+C{r}_2{O}_3$

$N{H}_{4}N{O}_2\stackrel{\Delta }{⟶}{N}_2+2H_{2}O$

$(N{H}_4{)}_{2}S{O}_4\stackrel{\Delta }{⟶}2N{H}_3+H_{2}S{O}_4$

$Ba(N_3{)}_2\stackrel{\Delta }{⟶}Ba+3N_2$

Among all the given compounds, only $(N{H}_4{)}_{2}S{O}_4$ do not form dinitrogen on heating, it produces ammonia gas.
