Dovator [93]3 years ago
4 0

Answer:

<em>The correct option is B) two liquids are mixed at room temperature and a gas forms.</em>

Explanation:

A chemical change can be described as a change which results in the formation of a new substance by the reactants. In the option B, two liquids react  to form a new product which is a gas. Hence, it is an example of chemical change.

Other options,like option D, is not a chemical change as by crushing a solid no new product is formed. Option C is also not correct because as when salt dissolves in water, no new product is made.
