State whether the following statements are true or false. In case a statement is false, write the corrected statement in your notebook
Iron and rust are the same substances. (True/False)

Explanation

To determine whether the statement "Iron and rust are the same substances" is true or false, we can follow these steps:

### Step 1: Understand the Definitions
- **Iron**: Iron is a metallic element with the chemical symbol Fe. It is a pure substance and is known for its strength and malleability.
- **Rust**: Rust is a common term for iron oxide, which forms when iron reacts with oxygen and moisture in the environment. The chemical formula for rust is typically represented as Fe₂O₃·nH₂O, indicating that it contains water molecules.

### Step 2: Analyze the Statement
The statement claims that iron and rust are the same substances. To evaluate this, we need to consider their definitions and chemical compositions.

### Step 3: Compare the Two Substances
- Iron is a pure metal, while rust is a compound formed from the reaction of iron with oxygen and moisture.
- Since rust is a product of a chemical reaction involving iron, they cannot be the same substance.

### Step 4: Conclusion
Based on the definitions and the chemical nature of both substances, we conclude that the statement is **false**.

### Corrected Statement
The correct statement would be: "Iron and rust are different substances."
