Here are the solutions to your chemistry questions. 1. a) Step 1: Balance the chemical equation. ZnO + 2HCl → ZnCl_2 + H_2O Step 2: Write the word equation. Zinc oxide + Hydrochloric acid → Zinc chloride + Water b) Step 1: Balance the chemical equation. (It is already balanced.) MgO + H_2SO_4 → MgSO_4 + H_2O Step 2: Write the word equation. Magnesium oxide + Sulfuric acid → Magnesium sulfate + Water c) Step 1: Balance the chemical equation. (It is already balanced.) ZnO + H_2SO_4 → ZnSO_4 + H_2O Step 2: Write the word equation. Zinc oxide + Sulfuric acid → Zinc sulfate + Water d) Step 1: Balance the chemical equation. MgO + 2HCl → MgCl_2 + H_2O Step 2: Write the word equation. Magnesium oxide + Hydrochloric acid → Magnesium chloride + Water 2. Magnesium oxide is a basic oxide. When it reacts with water, it forms magnesium hydroxide (Mg(OH)_2), which is a sparingly soluble base. The solution formed will be alkaline. If a universal indicator is added, it will turn blue or purple, indicating a pH greater than 7. 3. Step 1: Write the unbalanced chemical equation for the reaction between magnesium oxide and hydrochloric acid. MgO + HCl → MgCl_2 + H_2O Step 2: Balance the equation by ensuring the number of atoms for each element is the same on both sides. MgO + 2HCl → MgCl_2 + H_2O That's 2 down. 3 left today — send the next one.
