Question
Write a balanced chemical equation to represent decomposition of lead nitrate onheating. What are brown fumes due to?
Solution
The decomposition of lead nitrate upon heating can be represented by the following balanced chemical equation:
2Pb(NO3)2(s) → 2PbO(s) + 4NO2(g) + O2(g)
The brown fumes produced in this reaction are due to nitrogen dioxide (NO2).
