B. Gases form homogeneous mixtures with one another in any proportion.

C. The densities of gases are much larger than those of corresponding liquids.

D. A sample of gas assumes the shape and volume of its container.

C. The densities of gases are much larger than those of corresponding liquids.

Explanation:

Which is not a property of a gas? Select one:

A. Gases are highly compressible. It is a property of gases. The molecules of the gases occupy a minor fraction of the container they are in. As a consequence, the gas can be compressed and the molecules can occupy the previously empty space.

B. Gases form homogeneous mixtures with one another in any proportion. It is a property of gases. Gases can diffuse and mix with others in any proportion. Gaseous mixtures are always homogeneous.

C. The densities of gases are much larger than those of corresponding liquids. It is NOT a property of gases. Density is equal to mass divided volume. Since gases have larger volumes, their densities are lower than those corresponding to liquids.

D. A sample of gas assumes the shape and volume of its container. It is a property of gases. Gases do not have their own shape nor volume, so they adapt to their container.

E. The density of a gaseous substance varies strongly with temperature. It is a property of gases. According to Charle's Law there is a direct proportionality between the temperature of a gas and its volume. If the volume increases, the density decreases.
