slide 9: what is mud a mixture of? slide 10: why is air considered a mixture of gases? slide 11: how can be mixtures classified? what makes them different?
Answer
Brief Explanations:
- Slide 9: Mud is a mixture of soil and water. The soil particles are suspended in water.
- Slide 10: Air is considered a mixture of gases because it contains nitrogen, oxygen, carbon - dioxide, argon and other trace gases. These gases are not chemically combined and can be separated by physical means.
- Slide 11: Mixtures can be classified as homogeneous and heterogeneous. Homogeneous mixtures have a uniform composition throughout, like salt - water solution. Heterogeneous mixtures have non - uniform composition, like a mixture of sand and water. The main difference is the uniformity of composition.
