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
