Question

Name the type of mixture that is formed by the grains containing stones.

Answer 1

Mixtures:

1. A mixture is defined as a substance made up of two or more chemical compounds or substances that do not combine chemically.
2. It's a physical mixture of two or more substances that can maintain their identities even when mixed in the form of solutions, suspensions, or colloids. They can be separated through physical means.
3. Some properties of Mixtures are the proportions of the substances in the mixture vary, Despite the fact that no force is operating between the two or more substances, they are existing, The mixture's components are either homogenous or heterogeneous.
4. Sand and water, salt and water, and sugar and salt are some examples of mixtures.

Homogenous mixtures:

1. Homogeneous Mixtures are those that have a consistent composition throughout the substance.
2. The particles in these mixtures are smaller than one nanometer in size. They do not show Tyndall's effect.
3. It is impossible to distinguish particle boundaries. We cant use centrifugation to separate the constituent particles here.
4. Example: steel, air

Heterogeneous mixtures:

1. Heterogeneous Mixtures are those that are not uniform throughout.
2. Here, the constituent particles are not evenly distributed. We can effectively separate the components.
3. The particles here are between one nanometer and one micrometer in size.
4. They show Tyndall's effect.
5. Example: Chocolate chips in cupcakes, cereals in milk
6. As the mixture grain containing stones is a heterogeneous mixture because the particles are not uniform, we can separate them by physical means.

Therefore, the mixture that is formed by the grains containing stones is a heterogeneous mixture.
