(a)
Interpretation: The balanced chemical equation for the reaction of barium oxide with dioxygen should be given.
Concept introduction:
A chemical equation consists of reactants and products. The two are separated by an arrow. Each substances of reactants and products are separated from other by a plus sign. The reactants lies on left hand side while products lies on right hand side of the reaction.
A balanced chemical equation occurs when the number of atoms in reactant side is equal to the number of atoms in the product side.
(b)
