Na+Cl2 —>
Fe+S2–>
Synthesis reactions balance them

Answer 1

Let's balance the provided synthesis reactions step by step.

1. **Sodium and Chlorine Reaction**:
The reaction of sodium (Na) and chlorine gas (Cl₂) produces sodium chloride (NaCl). The unbalanced reaction looks like this:
\[
\text{Na} + \text{Cl}_2 \rightarrow \text{NaCl}
\]

To balance this reaction:
- There are 2 chlorine atoms in Cl₂ and only 1 chlorine atom in NaCl.
- Therefore, we need 2 NaCl to balance the chlorine.

The balanced equation is:
\[
2 \text{Na} + \text{Cl}_2 \rightarrow 2 \text{NaCl}
\]

2. **Iron and Sulfur Reaction**:
The reaction of iron (Fe) and sulfur (S) typically produces iron sulfide (FeS). The unbalanced reaction looks like this:
\[
\text{Fe} + \text{S} \rightarrow \text{FeS}
\]

To balance the reaction:
- The equation is already balanced as there is 1 iron atom on both sides and 1 sulfur atom on both sides.

The balanced equation is:
\[
\text{Fe} + \text{S} \rightarrow \text{FeS}
\]

So, the final balanced equations for the reactions are:
1. \( 2 \text{Na} + \text{Cl}_2 \rightarrow 2 \text{NaCl} \)
2. \( \text{Fe} + \text{S} \rightarrow \text{FeS} \)
