### For Paint
1. **Is the mixture homogeneous or heterogeneous?**
Heterogeneous.
2. **Is it a solution, suspension, or colloid?**
Suspension.
3. **Explain your classification.**
Paint typically contains solid pigments suspended in a liquid medium, and the particles can settle when left undisturbed, indicating a suspension. The presence of these visible particles means that paint does not achieve a uniform composition throughout.

### For Orange Juice
1. **Is the mixture homogeneous or heterogeneous?**
Heterogeneous.
2. **Is it a solution, suspension, or colloid?**
Suspension.
3. **Explain your classification.**
Orange juice often contains pulp and other solid particles that do not dissolve completely in the liquid, making it a suspension. Because you can see these particles and they can settle over time, it is classified as heterogeneous.

### For Soda
1. **Is the mixture homogeneous or heterogeneous?**
Homogeneous.
2. **Is it a solution, suspension, or colloid?**
Solution (specifically, a carbonated solution).
3. **Explain your classification.**
Soda is a homogeneous mixture where sugar and carbon dioxide gas are dissolved in water, resulting in a uniform distribution of ingredients throughout the liquid. The bubbles of carbon dioxide may be visible, but they do not affect the overall uniformity of the mixture.

### For Salad Dressing (Example)
1. **Is the mixture homogeneous or heterogeneous?**
Heterogeneous.
2. **Is it a solution, suspension, or colloid?**
Suspension.
3. **Explain your classification.**
Salad dressing, especially vinegar-based ones, often contain oil and various solid spices that do not fully integrate, leading to visible separation of components. This lack of uniformity indicates that it is a heterogeneous mixture and functions as a suspension.
