Give the correct balanced equation for the single replacement reaction of magnesium with aluminum oxide. A) Mg + AlO → MgO + Al
solniwko [45]
Answer is "C".

<em><u>Explanation
</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. 

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.
Here, 
 <em>Left Hand Side has </em>                                            <em>Right Hand Side has</em>
   Mg = 1 atom                                                         Mg = 1 atom
   Al = 2 atom                                                           Al = 1 atom
   O = 3 atom                                                           O = 1 atom

First step : balance the O atoms in both sides. To do that "3" should be added before MgO. 

Second step : After balancing O atoms, there will be 3 Mg atoms in right hand side. Hence to balance Mg atoms again "3" should be added before Mg in left hand side

Third step : as the final step balance the Al atoms by adding "2" before Al in the right hand side.

Then final balanced equation should be 
              3Mg + Al₂O₃ → 3MgO + 2Al
