Question

On strongly heating Pb(NO3)2 crystals, the gas formed is (A) NO2 (B) O2 (C) NO2 + O2 (D) NO

Tardigrade Admin · Accepted Answer

When solid lead nitrate is heated strongly a it turns yellow due to formation of lead oxide and a reddish brown gas is evolved which is nitrogen dioxide. 2Pb(NO3)2(s) arrow 2PbO(s) + 4NO2(g) + O2(g)

Q. On strongly heating $P b (N O_{3})_{2}$ crystals, the gas formed is

$N O_{2}$

$O_{2}$

$N O_{2} + O_{2}$

$NO$

When solid lead nitrate is heated strongly a it turns yellow due to formation of lead oxide and a reddish brown gas is evolved which is nitrogen dioxide.
$2 P b (N O_{3})_{2} (s) \to 2 P b O (s) + 4 N O_{2} (g) + O_{2} (g)$
