which of the following is a chemical property?

A. Color
B. Hardness
C. Freezing point***
D. Ability to react with oxygen
Can someone please check my answer???

Freezing point is a physical change. Physical changes don't change the substance; i.e., it is watr (as an example) as a liquid or in a solid (ice) but it's still water as in H2O. A chemical change is something where the substance is altered.

Thanks for the help!

Your answer is correct!

The ability to react with oxygen is a chemical property.

To determine which of the options is a chemical property, let's define what a chemical property is. A chemical property refers to a characteristic or behavior of a substance that can only be observed or measured during a chemical reaction.

Now, let's consider each option:

A. Color: This is a physical property, as it can be observed without any chemical changes occurring.

B. Hardness: This is also a physical property, as it can be determined by measuring the resistance of a substance to being scratched or deformed.

C. Freezing point: This is correct! Freezing point is a chemical property since it involves the conversion of a substance from a liquid to a solid state, which is a chemical change.

D. Ability to react with oxygen: This is also a chemical property as it describes the reactivity of a substance with oxygen, resulting in a chemical reaction.

Therefore, the correct answer is C. Freezing point. Well done!
