A) 2Mg + O2 —-> 2MgO | B) 2Mg + O —-> 2MgO |
C) 2Mg + O —-> MgO2 | D) 2Mg + O2 —-> MgO2 |
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.
