Answer:
2Mg(s) + O₂(g) → 2MgO(s)
Explanation:
2Ca(s) + Cl₂(g) → CaCl₂(s) (incorrect)
Ca(s) + Cl₂(g) → CaCl₂(s) (correct)
Li(s) + Cl₂(g) → 2LiCl(s) (incorrect)
2Li(s) + Cl₂(g) → 2LiCl(s) (correct)
2C(s) + O₂(g) → CO₂(g) (incorrect)
C(s) + O₂(g) → CO₂(g) (correct)

The correct answer is [tex]2Mg + O_2----> 2MgO[/tex]
Q. What is the balanced reaction?
- The balanced reaction states that the number of moles presents equally at both sides of the reaction that is a product and the reactant.
- The number of atoms is must be equal on both the side
All the other options are incorrect as the number of moles and atoms are not present in a stoichiometric manner and are not in equal proportion.
In the second equation, the number of atoms in the magnesium and oxygen is equal which is 2 on each side.
The number of atoms in the reactant is 2Mg and 2O and the number of atoms in the product is 2Mg and 2O.
Hence, the correct answer is B that is [tex]2Mg + O_2----> 2MgO[/tex]
