Astudent is using a copper strip and a strong chlorine solution in her experiment. which of these is a chemical property of one of her materials? density of the copper strip reactivity of the copper strip odor of the chlorine solution color of the chlorine solution

reactivity of the copper strip

Explanation: A physical property is defined as the property which measures change in shape and  size.No new substance gets formed in a physical change.

Example: Density of copper strip, Odor of chlorine solution and color of the chlorine solution.

A chemical property is defined as the property which measures change in chemical composition. A new substance is formed in chemical reaction.

Example: reactivity of substance

Reactivity of the copper strip

Explanation:

The matter properties can be classified as chemical property or physical property. The first refers to the properties that, when analyzed, change the composition of the matter, it means that a chemical property is a capacity of a substance to transform in other, such as the combustibility (the property to react with a comburent to form carbonic gas), the oxidation, and in general the reactivity.

The physical properties are the ones that are possible to be analyzed without changing the composition of a substance, such as the color, the density, the odor, and the pH.

So, the density of the copper strip, odor of the chlorine solution, and color of the chlorine solution are physical properties, and the reactivity of the copper strip is a chemical property.
