Question
A student modeled the exothermic synthesis reaction that occurs when solid iron and liquid sulfur chemically react to produce solid iron (ii) sulfide. The chemical reaction and the student’s model are shown below. Identify the two things in the model that need to be corrected.
### Chemical Reaction: \[ \text{Fe (s) + S (l) → FeS (s)} \]

#### Before the Reaction:
- **Diagram Description:**
  - The diagram shows two separate circles representing the reactants before the reaction-taking place.
    - Orange circle labeled "Fe" (solid iron).
    - Yellow circle labeled "S" (liquid sulfur).

#### After the Reaction:
- **Diagram Description:**
  - The diagram shows two overlapping circles representing the products after the reaction has taken place.
    - Orange circle still labeled "Fe" (now part of iron sulfide compound).
    - Yellow circle labeled "S" (now part of iron sulfide compound).

### Potential and Kinetic Energy Distributions:
- **Potential Energy:**
  - **Before Reaction:**
    - For the system: Four gray blocks are stacked within a column.
    - For the surroundings: Half of the column is gray, representing lesser potential energy compared to the system.
  - **After Reaction:**
    - For the system: Column shows the same four gray blocks as before.
    - For the surroundings: Column shows more potential energy compared to the system, indicated by the increased number of gray blocks compared to before the reaction.

- **Kinetic Energy:**
  - **Before Reaction:**
    - For the system: Column is half filled with gray blocks.
    - For the surroundings: Column is completely filled with gray blocks.
  - **After Reaction:**
    - For the system: Column shows more kinetic energy, indicated by an increased number of gray blocks compared to before.
    - For the surroundings: Column shows lesser kinetic energy compared to the system, with fewer gray blocks than before.

### Explanation:
- This chart illustrates the changes in potential and kinetic energy during the chemical reaction.
- **Before the Reaction:** The substantive part of the system's energy is potential energy, whereas the surrounding energy is mostly kinetic.
- **After the Reaction:** There is a notable shift where the system now exhibits increased kinetic energy and the surroundings demonstrate increased potential energy, showcasing the transfer and transformation of energy types during the reaction process.
