Answer 2

Hi

Here is your answer

2Pb(NO₃)₂  (Δ)→  2PbO +  4NO₂  + O₂

Pb(NO₃)₂ - Lead Nitrate

PbO - Lead Oxide

NO₂ - Nitrogen Oxide

O₂ - Oxygen

When lead nitrate is heated Pb burns in yellow colour and brown colour NO₂ gas evolved.

When this is passes into wooden splinter it catches fire.

This shows the presence of Oxygen.

Hope it helps U..... :-)
