What are chemical properties (apex)

a. properties that can change the chemical nature of matter

b. the difference between
a substance and a mixture

c. the difference between a heterogeneous and a homogeneous mixture

d. characteristics used to tell the difference between matter

Option (A) is the correct answer.

Explanation:

A property that changes chemical nature of a substance is known as chemical property.

For example, reactivity, toxicity, combustion etc are all chemical properties.

Whereas a property which does not change the chemical property of a substance is known as a physical property.

For example, mass, density, volume etc are all physical properties.

Therefore, we can conclude that properties that can change the chemical nature of matter are called chemical properties.
