Question

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

A.

Oxidation reaction

B.

Reduction reaction

C.

Double displacement reaction

D.

Displacement reaction

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+12O2MgO{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.
