Hey dear,

● Answer -
Gas evolved in this reaction is oxygen gas.

● Explaination -
Lead oxide reacts with conc. HNO3 to give lead nitrate.
2PbO2 + 4HNO3 --> 2Pb(NO3)2 + 2H2O + O2

Oxygen gas is released in this reaction.

Lead oxide being a strong oxidizing agent, can oxidize HNO3 to O2.

Hope this helps you.
Thanks for asking..
