Balance the following equation:
Balanced chemical equation:
A chemical equation in which the numbers of atoms of each element on both th sides of the equation is equal is called balanced equation.
Step 1 : Representation of the chemical reaction
2Pb(NO3)2 →2PbO + 4NO2 + O2
Step 2 : Calculating the number of atoms on both side of reaction
Elements | Number of atoms on reactant side | Number of atoms on product side |
Pb | 2 | 2 |
O | 12 | 12 |
N | 4 | 4 |
Step 3: Balancing the uneven numbers of atoms on both the side of reaction
Hence, the equation is balanced.
2Pb(NO3)2 (s) → 2PbO(s) + 4NO2 (g) + O2(g)
