Question

Magnesium reacts with carbon dioxide to form magnesium oxide and pure solid carbon.

Mg + CO2 --> MgO + C
This equation is not balanced. Why is it important for us to balance the equation for this reaction?

A. To show the conservation of mass.

B. To show the conservation of energy.

C. If it is not balanced, the reaction will not work.

Answer 1

2Mg + 2CO₂ → 2MgO + C

Option a.

Step-by-step explanation:

The chemical reactions are balanced in order to verify compliance with the Law of conservation of mass. This law states that in any chemical reaction, the mass of the reagents must be equal to the mass of the products
