Identify the solutions among the following mixtures. (a) Soil, (b) sea water, (c) air, (d) coal, (e) soda water

Explanation

To identify the solutions among the given mixtures, we need to understand the difference between homogeneous and heterogeneous mixtures. A solution is a type of homogeneous mixture where the components are uniformly distributed.

### Step-by-Step Solution:

1. **Understand the Definitions**:
- **Homogeneous Mixture**: A mixture with a uniform composition throughout. The components are evenly distributed and cannot be easily distinguished.
- **Heterogeneous Mixture**: A mixture where the components are not uniformly distributed and can be easily distinguished.
