Answer
EqualsThe four types of mixtures include the following:1. **Homogeneous Mixtures (Solutions):** Uniform distribution and proportional content. For example, the air we breathe.2. **Heterogeneous Mixtures:** Non-uniform distribution and can distinguish visually distinct components. For example, a pizza.3. **Suspension Mixtures:** Heterogeneous with large, separate solutes. Needs consistent disturbance to maintain uniformity. For example, sand in the water.4. **Colloid Mixtures (Microscopic heterogeneity):** Can not be easily separated by mechanical means because of microscopic heterogeneity. For example, milk.
Explanation
## Step 1:Mention what mixtures are:Mixtures are materials made up of two or more different substances which are mixed but are not combined chemically. ## Step 2:Discuss the four types of mixtures, their features, and examples for each:Firstly, we have homogeneous mixtures, also known as solutions. In a Homogeneous mixture, substance present in the mixture shows the same proportional amount of its content throughout. Additionally, each of the individual substances remains uniformly distributed in the mixture. An example can be the air we breathe, which is a mixture of many gases with Nitrogen, Oxygen being the major components.Secondly, the heterogeneous mixtures. Unlike the former, the substances present are not uniformly distributed, and they can be visually horizontally and verticallya distinguished in general. The examples include a sand-water mixture, a pizza etc.Thirdly, the suspension mixtures. Suspensions are heterogeneous mixtures with large, often visible solutes that tend to settle over time. The suspension needs continuous mixing to maintain its uniformity. Take the sand in water as an example, if the mixture isn't stirred, the sand will soon settle to the bottom. Lastly, we have colloid mixtures or microscopic heterogeneity. In this distinct subtype of heterogeneous mixtures, particles do not settle when the mixture stands for a while. The components of a colloid are spread out evenly, yet cannot be separated easily by mechanical means due to the lack of visible segregation of components. For example, milk is a colloid of protein in water along with others.
