The Law of Conservation of MASS, ENERGY, and CHARGE
The volume is changed.
Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.

Chemical (Apex)
The valence electrons are the part that takes place in a chemical reaction.
chemical reaction takes place in rancidity
It depends on the reaction. An exothermic reaction releases (liberates) energy and an endothermic reaction absorbs energy.
These initial substances are the reactants.

It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.
