**Step-by-Step Solution:** 1. **Understanding the Reactants**: When magnesium oxide (MgO) is dissolved in water (H₂O), a reaction occurs. Magnesium oxide is a white solid, and water is a liquid. 2. **The Reaction**: When magnesium oxide is added to water, it reacts to form magnesium hydroxide (Mg(OH)₂). This is a chemical reaction where a new substance is produced. 3. **Writing the Word Equation**: The word equation for this reaction can be written as: - Magnesium Oxide + Water → Magnesium Hydroxide ...
