Identify the correct statement(s).

Options

A. Mixtures which have a uniform composition throughout are called homogeneous mixtures or solutions.
B. A homogeneous mixture can have a variable composition.
C. Heterogeneous mixtures have non-uniform compositions.
D. All of these

Answer

To solve the question "Identify the correct statement(s)", we will analyze the definitions and characteristics of mixtures, homogeneous mixtures, and heterogeneous mixtures based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding Mixtures**:
- A mixture is formed when two or more substances are combined.
- The key characteristic of a mixture is that its components can be physically separated.

2. **Types of Mixtures**:
- There are two main types of mixtures: homogeneous and heterogeneous.

3. **Homogeneous Mixtures**:
- Homogeneous mixtures have a uniform composition throughout.
- This means that the substances are mixed well and you cannot distinguish the individual components.
- An example of a homogeneous mixture is sugar dissolved in water, where the sugar is evenly distributed.

4. **Heterogeneous Mixtures**:
- Heterogeneous mixtures have a non-uniform composition.
- In these mixtures, you can see distinct phases or components.
- An example of a heterogeneous mixture is sand in water, where the sand settles at the bottom and is visibly separate from the water.

5. **Correct Statements**:
- Based on the definitions:
- Mixtures can be physically separated.
- Homogeneous mixtures have a uniform composition.
- Heterogeneous mixtures have a non-uniform composition.
- Therefore, all the statements regarding mixtures are correct.

6. **Conclusion**:
- The correct answer to the question is that all the statements provided are correct.

### Final Answer:
- All of the statements regarding mixtures are correct.
