Question

When lead nitrate is heated it give PbO , NO2 and O2 the correct no of moles of Pb(NO3)2, PbO ,NO2 and O2 are respectively
(a) 2,2,4,1 (b) 1,2,2,4 (c) 2,2,1,4 (d) 1,2,4,1

Answer 1

Explanation:

Decomposition reaction is reaaction in which compound break down into two or more simpler substances.

2Pb(NO3 ) 2 ⟶2PbO+4NO 2 +O 2

This reaction is an example of decomposition reaction. Pb(NO3 ) 2 decomposes in PbO,NO 2

and O 2 .

Answer 2

(a) is the correct answer.
