Which statement describes evidence of a chemical reaction?
a. ice melting
b. water boiling
c. lighting a match
d. grape juice freezing

c. lighting a match

Explanation:

ice melting water is a physical change. The chemistry of the substance in question does not change. It is water before the the melting and water after the melting, in different physical states.

The same is true with boiling water, the chemistry of the water does not change. It's physical state changes from liquid to gas.

Grape juice freezing is also a physical change where the physical state changes from liquid to solid. This is easily reversible by melting and liquid grape juice becomes available.

Lighting a match however is a chemical reaction, it is not a physical change. The products have a different chemistry when compared to the reactants and the process is difficult if not impossible to reverse, which is another characteristic of chemical changes
