Chemistry Chapter 2.2

What is a mixture?

• A physical blend of two or more components

• A chemical reaction between two or more components

• A single pure substance

• A compound formed by chemical bonds

How can mixtures be classified based on the distribution of their components?

• As either solutions or suspensions

• As either elements or compounds

• As either homogeneous or heterogeneous mixtures

• As either solids or liquids

What term is used to describe any part of a sample with uniform composition and properties?

• Phase

• Element

• Compound

• Mixture

What process is used to separate components of a mixture using different boiling points?

• Filtration

• Distillation

• Chromatography

• Decantation

What process is used to separate ground coffee beans from the brewed coffee?

• Filtration

• Distillation

• Evaporation

• Sedimentation

What is a phase in the context of mixtures?

• A phase is any part of a sample with uniform composition.

• A phase is a part of a sample with varying composition.

• A phase is a part of a sample with no composition.

• A phase is a part of a sample with random composition.

How many phases does a homogeneous mixture have?

• One

• Two

• Three

• Four

In a homogeneous mixture, the composition is:

• Uniform throughout

• Varying throughout

• Random throughout

• None of the above

In a heterogeneous mixture, the composition is:

• Uniform throughout

• Varying in different parts

• Random throughout

• None of the above

Which mixture type can have varying composition in different parts?

• Homogeneous

• Heterogeneous

• Both homogeneous and heterogeneous

• Neither homogeneous nor heterogeneous
