2 Ca ( NO 3)2 stackrelΔ longrightarrow 2 CaO + O 2+4 NO 2 Ca gives brick red colour and nitrate gives O 2 and brown gas of NO 2

Q. A substance which gives brick red flame and breaks down on heating to give oxygen and a brown gas is:

Magnesium nitrate

Calcium nitrate

Barium nitrate

Strontium nitrate

$2 C a (N O_{3})_{2} ⟶ Δ 2 C a O + O_{2} + 4 N O_{2}$

Ca gives brick red colour and nitrate gives $O_{2}$ and brown gas of $N O_{2}$
