Question

which of the following are chemical properties of matter? answer: a mass b volume c density d flammability

Explanation:

To determine the chemical property, we analyze each option:

• Option A (mass): Mass is a physical property (amount of matter, measurable without chemical change).
• Option B (volume): Volume is a physical property (space occupied, no chemical change needed to measure).
• Option C (density): Density (mass/volume) is a physical property (determined without altering chemical identity).
• Option D (flammability): Flammability describes a substance’s ability to burn (undergo combustion, a chemical reaction), so it is a chemical property.

Answer:

D. flammability
