Question
A reddish brown gas is released on heating lead nitrate. The type of reaction involved here is:
Answer: Option C
:
C
A decomposition reaction is where one reactant is broken into multiple simple products.
When lead nitrate (2Pb(NO3)2) is heated, it decomposes into lead oxide (PbO), nitrogen dioxide (NO2) and oxygen (O2). The reaction occurs as follows:
2Pb(NO3)2(s)Heat⟶2PbO (s)+4NO2(g)+O2(g)
Thereddish brown gas released is NO2.
