Asubstance did not change its chemical nature in a reaction. which most likely describes the reaction? a. it was heated. b. it was hit with a hammer. c. it was placed in a salt solution. d. it was frozen.

For example,

A chemical change will always lead to the formation of a new compound.

Thus, we can conclude that it was frozen most likely describes the reaction.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
