Which of the following is a chemical property of a substance?
A.
Density
B.
Melting point
C.
Boiling point
D.
Reactivity with acid
Correct Answer : D
The correct answer is:
D. Reactivity with acid
Explanation:
- Chemical properties refer to how a substance reacts with other substances and involves a change in its chemical composition. Reactivity with acid is a chemical property because it involves a chemical reaction where the substance changes into different substances.
- A. Density, B. Melting point, and C. Boiling point are physical properties. Density measures mass per unit volume, melting point is the temperature at which a solid turns into a liquid, and boiling point is the temperature at which a liquid turns into a gas. These properties describe physical characteristics and do not involve a change in chemical composition.
