An example of a chemical property is —

A. mass of a substance per unit volume
Incorrect. This is density, which is physical.

B. ability to dissolve in solution
Incorrect. This is solubility, which is a physical property.

C. point where solid becomes liquid
Incorrect. This is the melting point which is a physical property.

D. tendency to undergo oxidation
Correct! This only becomes apparent after the substance undergoes oxidation.

Which grouping identifies chemical properties?

A. Density, luster, boiling point
Incorrect. All of these are physical properties.

B. Melting point, hardness, conductivity
Incorrect. All of these are physical properties.

C. Malleability, ductility, texture
Incorrect. All of these are physical properties.

D. Combustibility, flammability, reactivity
Correct! All of these are chemical properties.

Which of the following is an intensive physical property?

A. Mass
Incorrect. This is an extensive physical property because mass changes.

B. Volume
Incorrect. This is an extensive physical property because volume changes.

C. Reactivity
Incorrect. This is a chemical property.

D. Color
Correct! You can use color to help identify the substance.

Which statement describes a chemical property that can be used to distinguish between compound A and compound B?

A. A does not burn in air, and B does burn in air.
Correct! The ability for a substance to burn is a chemical property.

B. A has a high boiling point, and B has a low boiling point.
Incorrect. The temperature in which a substance boils is a physical property.

C. A dissolves in water, and B does not dissolve in water.
Incorrect. The solubility of a substance is a physical property.

D. A is a red solid, and B is a white solid.
Incorrect. Color is a physical property.

Which of the following is an extensive property of a liquid?

A. percent oxygen
Incorrect. This would be an intensive property.

B. Density
Incorrect. This would be an intensive property.

C. Weight
Correct! A 1 meter iron rod will weigh less than a 3 meter iron rod. Yet the substance is iron in both sizes.

D. Odor
Incorrect. This would be an intensive property.
