What is a heterogeneous mixture?

• A mixture that is a pure substance

• A mixture where different materials are easily identifiable

• A mixture where substances are uniformly spread out

• A mixture that cannot be separated by physical means

Answer explanation

A heterogeneous mixture is a mixture where different materials are easily identifiable, unlike a homogeneous mixture where substances are uniformly spread out.

Which of the following is a homogeneous mixture?

• Fruit salad

• Vinegar

• Gold

• Helium

Answer explanation

The correct choice is Vinegar because it is a homogeneous mixture, meaning it has a uniform composition throughout.

What is a pure substance?

• A type of matter that can be separated by physical means

• A material made up of different elements

• A type of matter with a fixed composition that cannot be separated by physical means

• A mixture of two or more substances

Answer explanation

A pure substance is a type of matter with a fixed composition that cannot be separated by physical means, distinguishing it from mixtures.

Which of the following is NOT a characteristic of a compound?

• Has a fixed composition

• Can be separated by physical means

• Made up of atoms of two or more elements

• Examples include water and carbon dioxide

Answer explanation

The correct choice is 'Can be separated by physical means' because compounds cannot be separated by physical means, unlike mixtures which can be separated through physical processes like filtration or distillation.

Which of the following is an example of a heterogeneous mixture?

• Carbon dioxide

• Fruit salad

• Vinegar

• Saltwater

Answer explanation

Fruit salad is an example of a heterogeneous mixture because it contains different types of fruits that are not chemically combined, unlike the other options.

Identify two examples of compounds.
