Question

Write a balanced chemical equation to represent decomposition of lead nitrate on heating what are brown fumes due to

Answer 1

Hey.....

when heat is passed through lead nitrate then it decompose into lead oxide ,Nitrogen oxide and oxygen gas...

Here us it's balanced equation..

2Pb(NO3)2 -------->2PbO + 4NO2 + O2......

Hope this will help u...

Answer 2

when lead nitrate is heated .thermal decomposition reaction takes place as follows

2Pb(NO3)2 (s) + heat -------> 2PbO (s) + 4NO2 (g) + O2 (g)

here Pb(NO3)2 is lead nitrate.

PbO is lead oxide,nitrogen dioxide[NO2​] which appears as brown fumes and oxygen is produced.
