Question

which of the following describes a chemical property? *
mass
volume
state of matter
reactivity
which of the following describes a physical property? *
color
flammability
rust formation
reactivity with oxygen
students observed that mixing two clear solutions formed a white solid and released heat.
which two terms best describe this reaction?

Explanation:

• Chemical property: A chemical property is a characteristic of a substance that is observed during a chemical reaction. Reactivity is a chemical property as it involves the ability of a substance to undergo a chemical change. Mass, volume, and state of matter are physical properties as they can be measured without changing the substance's chemical identity.
• Physical property: A physical property is a characteristic that can be observed or measured without changing the substance's chemical identity. Color is a physical property. Flammability, rust formation, and reactivity with oxygen are chemical properties as they involve chemical changes.

Answer:

• For the first question (chemical property): Reactivity
• For the second question (physical property): Color
