(b)
Interpretation:
The coefficients that balance the given equation has to be found out.
Concept Introduction:
Chemical reaction can be entered in form of a chemical equation. The total number of atoms of the same element in both sides of the arrow in a chemical equation has to be equal. Once, this is same, then the equation obtained is known as balanced chemical equation. For balancing chemical equation, the coefficients alone can be modified and not the subscripts of the atoms in the formula.
