Question

A scientist is trying to identify an unknown substance. The answer to which of the following questions would give the scientist information about a chemical property of the substance?. . Is it possible to change the shape of the substance? . . Does the substance corrode when left in water? . . What color is the substance? . . At what temperature does the substance melt? .

Answer 1

Step-by-step explanation:

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition identity of the substance gets changed. For example: color, reactivity etc.

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.

The question of which will give us information regarding chemical property of the substance will be:

Does the substance corrode when left in water?

This is because corrosion is the type of chemical reaction in which damaging of the surface of the substance takes place due to its surroundings.Here identity of the substance changes.Hence answering this question will give us an information regarding chemical property of the substance.

Answer 2

The one question that would give the scientist information about a chemical property of the substance is "Does the substance corrode when left in water?" The correct answer is B.
