Final answer:
Barium oxide reacts with water to produce barium hydroxide, represented chemically as BaO + H₂O → Ba(OH)₂, which is already balanced.
Step-by-step explanation:
The chemical reaction between barium oxide and water forms barium hydroxide. The reaction can be represented by both a word equation and a chemical equation.
Word equation: Barium oxide + Water → Barium hydroxide
Chemical equation: BaO + H₂O → Ba(OH)₂
To balance this equation, we start by writing the formulas of the reactants and the product. In this case, no additional balancing is required because the equation has an equal number of each type of atom on both sides.
