Question

which term identifies a chemical property that can be used to differentiate a sample of sodium from a samp a temperature b density c reactivity d mass back

Explanation:

To determine the correct answer, we analyze each option:

• Option A (temperature): Temperature is a physical property related to the kinetic energy of particles, not a chemical property. So it is incorrect.
• Option B (density): Density is a physical property that describes the mass per unit volume of a substance, not a chemical property. So it is incorrect.
• Option C (reactivity): Reactivity is a chemical property as it describes how a substance interacts and reacts with other substances (e.g., sodium's reactivity with water or oxygen). This can be used to differentiate sodium from other substances.
• Option D (mass): Mass is a physical property (the amount of matter in a substance) and not a chemical property. So it is incorrect.

Answer:

C. reactivity
