Question

What happens when lead nitrate is heated in a tube

Answer 1

HI! here is your 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 .When the evolved gas is passed over wooden glowing splinters it rekindles.This shows the presence of oxygen.

I hope it will help you.

Hence the Chemical equation for above reaction is-

2Pb(NO3)2→2PbO+4NO2+O2

Answer 2

When the lead nitrate is heated up then the lead nitrate decomposes the heat, and the nitrogen oxide appears to be the brown fumes, and then the oxygen is produced, but when the leas nitrate is heated up then it decomposes to lead nitrogen oxide, lead mono oxide and the oxygen.
