Question

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? slide 12: what are some characteristics of a homogeneous mixture? slide 13: how will you describe a heterogeneous mixture?

Explanation:

• Slide 9: Mud is a mixture of soil, water, and sometimes organic matter.
• Slide 10: Air is a mixture of gases because it contains nitrogen, oxygen, carbon - dioxide, argon and other trace gases that are not chemically combined.
• Slide 11: Mixtures can be classified as homogeneous (uniform composition throughout) or heterogeneous (non - uniform composition). The difference lies in the distribution of components; homogeneous mixtures have a single phase while heterogeneous have two or more phases.
• Slide 12: Characteristics of a homogeneous mixture include a single visible phase, uniform composition, and components that cannot be easily separated by physical means like filtration.
• Slide 13: A heterogeneous mixture has a non - uniform composition, multiple visible phases, and components that can often be separated by physical methods such as filtration or sedimentation.

Answer:

Slide 9: Soil, water, and sometimes organic matter.
Slide 10: It contains nitrogen, oxygen, carbon - dioxide, argon and other trace gases that are not chemically combined.
Slide 11: Classified as homogeneous or heterogeneous. Homogeneous has uniform composition and single phase, heterogeneous has non - uniform composition and multiple phases.
Slide 12: Single visible phase, uniform composition, components not easily separated by physical means like filtration.
Slide 13: Non - uniform composition, multiple visible phases, components can often be separated by physical methods such as filtration or sedimentation.
