In which of these classes must two or more substances be present? Homogeneous and Heterogeneous

Reason: As both are mixtures which can be obtained when two or more substances are present.

Pure substance will be only one kind of substance.

Which of these classes could not possibly have a variable composition: Pure substance

Reason: A pure substance cannot have variable composition: For example pure CO2 will always have one atom of carbon and two atoms of oxygen

For which of these classes is separation into simpler substances by physical means possible: Both homogeneous and heterogenous mixtures can be separated into simpler substances by physical means.
