Question

When sodium reacts with chlorine, sodium chloride is produced. Andrew represented this reaction with this equation: Na + Cl2 → 2NaCl

Answer 1

Answer:

The correct representation of reaction will be:

$2Na + Cl_2 \rightarrow 2NaCl$

Explanation:

$Na + Cl_2 \rightarrow 2NaCl$

Reaction represented by Andrew is not correct as it is not a chemical reaction balanced. Whenever a chemical reaction takes place mass of the reactants always remains conserved as a per as law of conservation of mass.

The law states that mass can neither be created nor be destroyed. And in a balanced chemical reaction number total mass of reactants is always equal to the total mass of products.

The correct representation of reaction will be:

$2Na + Cl_2 \rightarrow 2NaCl$

Number of sodium atoms and chlorine atoms on the both sides are equal

Answer 2

When sodium metal reacts with chlorine gas, the product would be sodium chloride or the table salt. The balanced chemical reaction would be:

2Na + Cl2 = 2NaCl

IN balancing reactions, it is important to remember that the number of atoms at each side should be equal. Hope this answers the question.
