The chemical equation below shows the reaction of sodium (na) and chlorine (cl) to form sodium chloride (nacl). 2na + cl2 → 2nacl in this equation, which of the following is a reactant? i. sodium ii. chlorine iii. sodium chloride a. i only b. i, ii, and iii c. i and ii only d. iii only

Answer : The correct option is, (C)  I and II only

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on the reactant side must be equal to the product side.

The given balanced chemical reaction is,

In the balanced chemical reaction, the species present on the left side of the reaction is known as reactant and the species present on the right side of the reaction is known as product.

From this we conclude that, the sodium, and chlorine, are the reactants and sodium chloride, is the product.

Hence, the correct option is, (C)  I and II only

the objects have the same charge is correct.
