(b)
Interpretation:
The number of atoms of each element on each side of the given equations is to be determined. Whether the equation is balanced or not is to be stated.
Concept introduction:
A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on both sides of the equation is equal.
