Consider this chemical equation:
[tex]\[2 \text{Na} (s) + \text{Cl}_2(g) \rightarrow 2 \text{NaCl} (s)\][/tex]

In this reaction, sodium [tex]\((\text{Na})\)[/tex] is:
[tex]\[\square\][/tex]

In this reaction, chlorine [tex]\((\text{Cl}_2)\)[/tex] is:
[tex]\[\square\][/tex]

In this reaction, sodium chloride [tex]\((\text{NaCl})\)[/tex] is:
[tex]\[\square\][/tex]



Answer :

Let's analyze the given chemical equation step-by-step:

The given chemical equation is:
[tex]\[ 2 \, \text{Na} \, (s) + \text{Cl}_2 \, (g) \rightarrow 2 \, \text{NaCl} \, (s) \][/tex]

This indicates a chemical reaction between sodium (Na) and chlorine (Cl₂) to form sodium chloride (NaCl).

1. Identify the reactants and the product in the equation.

- Reactants:
- Sodium (Na): The element sodium is in the solid state, denoted by (s).
- Chlorine (Cl₂): Chlorine is in the gaseous state, denoted by (g).

Hence, sodium [tex]\((\text{Na})\)[/tex] and chlorine [tex]\((\text{Cl}_2)\)[/tex] are the reactants.

- Product:
- Sodium chloride (NaCl): The compound formed is sodium chloride, which is in the solid state, denoted by (s).

Hence, sodium chloride [tex]\((\text{NaCl})\)[/tex] is the product.

2. Summarize the roles of each chemical species:

- Sodium (Na) is a reactant because it is one of the starting substances that undergoes a chemical change.
- Chlorine (Cl₂) is a reactant because it is another starting substance that combines with sodium to form the product.
- Sodium chloride (NaCl) is a product because it is the new substance formed as a result of the chemical reaction.

Therefore:
- In this reaction, sodium [tex]\((\text{Na})\)[/tex] is: reactant
- In this reaction, chlorine [tex]\((\text{Cl₂})\)[/tex] is: reactant
- In this reaction, sodium chloride [tex]\((\text{NaCl})\)[/tex] is: product
