Balance the above Chemical equation?

A) 2Mg + O2 ----> 2MgO B) 2Mg + O ----> 2MgO
C) 2Mg + O ----> MgO2 D) 2Mg + O2 ----> MgO2
 
Answer & Explanation Answer: A) 2Mg + O2 ----> 2MgO

Explanation:

Given Equation is 

Mg + O2  MgO

Balancing the Chemical Equation is nothing but Conservation of Matter. As Matter is Neither created nor Destroyed, it must be conserved.

Here we have 1 Mg and 2 O on the left side and 1 Mg and 1 O on the right side

To balance that, add 1 Mg on the left side so that it becomes 2 Mg and 2 O on the left side

i.e,

2 Mg + O2  2 MgO

Here it has 2 Mg & 2 O on the left side and 2 Mg and 2 O on the right side and the Chemical equation is Balanced.
