Question

Alkaline earth metal nitrates on heating decompose to give (A) M(N O2)2 and O2 only (B) MO, N2 and O2 (C) MO, NO2 and O2 (D) MO and NO2 only

Alkaline earth metal nitrates

Nitrates decompose as follows

MN O_{3} \to MN O_{2} + \frac{1}{2} O_{2}

At very strong heating

MN O_{3} \to M_{2} O + \frac{1}{2} O_{2} + N_{2}

except

L i

, it decomposes as follows

2 L i N O_{3} \to L i_{2} O + 2 N O_{2} + \frac{1}{2} O_{2}

Nitrates of alkaline earth metals decompose as follows,

M ((NO)_{3})_{2} \to MO + 2 (NO)_{2} + \frac{1}{2} O_{2}

For alkaline earth metals

M (N O_{3})_{2} \to MO (s) + 2 N O_{2} + \frac{1}{2} O_{2}
