<h3><u>Answer;</u></h3>
C. 3Mg + Al2O3 → 3MgO + 2Al
<h3><u>Explanation;</u></h3>
- <u><em>Single replacement reaction is a type of reaction which one reactant reacts with another and makes a product by replacing one element by another. </em></u>
- Mg (Magnesium) reacts with Al₂O₃ (Aluminium oxide) and produces MgO (Magnesium oxide) and Al (Aluminium) as products. Here Al is replaced by Mg. Reaction is
Mg + Al₂O₃ → MgO + Al
- To balance the reaction equation, both left and right hand sides should have same number of atoms in each element.
The balanced equation will be;
3Mg + Al2O3 → 3MgO + 2Al
