​Burning of magnesium in the presence of air produces magnesium oxide. Select the type of reaction involved. ​

Correct option is A

The correct answer is (A) oxidation reaction.

The burning of magnesium in the presence of air produces magnesium oxide. This is an oxidation reaction.  

Here's why:

• Oxidation: In this reaction, magnesium (Mg) loses electrons and combines with oxygen (O₂) from the air to form magnesium oxide (MgO).   $${Mg} + \frac{1}{2} {O_2} → {MgO}$$​​
• Key Characteristics of Oxidation:
• Loss of electrons
• Gain of oxygen  
• Increase in oxidation state  

Therefore, the burning of magnesium in air is an oxidation reaction.
