Write balanced chemical equations for the preparation of the following compounds (as the major product) starting from iron and using only one other substance:
Iron (II) sulphide

Explanation

To prepare Iron (II) Sulphide (FeS) starting from iron and using only one other substance, we can follow these steps:

### Step 1: Identify the Reactants
We need to start with iron (Fe) and use one other substance, which in this case will be sulfur (S).

### Step 2: Write the Unbalanced Equation
The unbalanced chemical equation for the reaction between iron and sulfur to form iron (II) sulphide is:
\[ \text{Fe} + \text{S} \rightarrow \text{FeS} \]
