Question

Balance the following equate aus
1) CH4 + O2
-> H₂O
2) Pb(NO3)2 + kl -> Pbl + KNO;​

Answer 1

C=1. H=4. O=4. As the number of atoms in the reactants side is equal to the number of atoms in the product side, the reaction is balanced.

Pb(NO3)2+ kl =Pbl+ KNO3 = On(NO3)2+ 2kl =) Pbl2 + 2KNO3.
