Question

question 1. a pure white, solid material that looks like table salt releases gas when heated under certain conditions. there is no change in the appearance, but the reactivity of the material changes. did a chemical or physical change occur? explain

Explanation:

A chemical change occurs when there is a change in the chemical composition and reactivity of a substance. In this case, the solid material releasing gas upon heating indicates a change in its chemical nature, even though the appearance remains the same. Physical changes only affect physical properties like state, shape, or size without altering the chemical composition.

Answer:

A chemical change occurred because the material released gas when heated, which indicates a change in its chemical reactivity and composition.
