How to balance a chemical equation with algebric method??
Open in App
Solution
Balancing of a chemical reaction is necessary for the determination of amount of compound formed in a reaction. It is balanced in following ways:
Balance the element on the basis of priority
Metal > Non-Metal > Oxygen > Hydrogen
Pb(NO3)2 → PbO +2NO2 + O2
Step-1 Check Number of Lead on L.H.S and R.H.S.
Pb(NO3)2 → PbO +2NO2 + O2
Step-2 Check Number of Nitrogen on L.H.S and R.H.S.
Pb(NO3)2 → PbO +2NO2 + O2
Step-3 Check the number of oxygen atom on L.H.S and R.H.S.
2Pb(NO3)2 → 2PbO +4NO2 + O2
Equation Balanced.
