( NH 4)2 Cr 2 O 7 xrightarrow text heat Cr 2 O 3+4 H 2 O + N 2 NH 4 NO 2 xrightarrowΔ 2 H 2 O + N 2

Q. $(N H_{4})_{2} C r_{2} O_{7}$ on heating liberates a gas. The same gas will be obtained by

Treating $H_{2} O_{2}$ with $N a N O_{2}$

Treating $M g_{3} N_{2}$ with $H_{2} O$

Heating $N H_{4} N O_{3}$

Heating $N H_{4} N O_{2}$

$(N H_{4})_{2} C r_{2} O_{7} heat C r_{2} O_{3} + 4 H_{2} O + N_{2}$
$N H_{4} N O_{2} Δ 2 H_{2} O + N_{2}$
