    1. Sea water:
    – Solution. Sea water is a homogeneous mixture where salt (and other dissolved substances) is uniformly distributed in water.

    2. Soda water:
    – Solution. Soda water is a homogeneous mixture of carbon dioxide gas dissolved in water, along with other additives.

    The other mixtures are not solutions:

    – Soil:
    – Heterogeneous mixture. Soil is composed of a variety of particles such as minerals, organic matter, water, and air, and it does not have a uniform composition.

    – Air:
    – Homogeneous mixture. While air is a mixture of gases, it is considered homogeneous because the gases are uniformly distributed throughout the atmosphere.

    – Coal:
    – Heterogeneous mixture. Coal consists of a variety of substances, including carbon, hydrogen, sulfur, and other elements, and its composition is not uniform.

    So, sea water and soda water are the solutions in this list.

    1. Soda Water:
    – Homogeneous mixture.
    – Uniform composition throughout.
    – Combination of water and dissolved gases.

    2. Vinegar:
    – Homogeneous mixture.
    – Displays uniform composition.
    – Solution of acetic acid in water.

    3. Air:
    – Homogeneous mixture.

    4. Wood:
    – Heterogeneous mixture.
    – Non-uniform appearance.
    – Composed of cellulose, lignin, and other substances.

    5. Soil:
    – Heterogeneous mixture.
    – Non-uniform due to varied components.
    – Contains minerals, organic matter, water, and air pockets.

    6. Filtered Tea:
    – Homogeneous mixture.
    – Solutes evenly dispersed in the liquid.
    – Uniform composition in the filtered state.

    7. Scale of Observation:
    – Classification can depend on the scale of observation.
    – Wood may appear homogeneous on a small scale but reveals heterogeneity at a larger scale.
    – The distinction between homogeneous and heterogeneous mixtures is based on the uniformity or lack thereof in their compositions and appearances.
