Question

please anyone show me the steps how to balance this equation by counting the no.of atoms in lhs and rhs....
PB(NO3)2------->PbO+NO2+O2​

Answer 1

Answer:

Explanation:

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

LHS RHS

O=6 O=5

So, make PbO as 2PbO

Pb=1 Pb= 2

So, make

Pb(NO3)2 as

2Pb(NO3)2

Now,

N=4 N=1

Make NO2 as 4NO2

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

Pb=2 Pb=2

N=4 N=4

O=12 O=12

LHS=RHS

Equation is balanced
