It solely depends on the reactions.
Depends on what type/kind of chemicals!!!
This reaction is a chemical change.
It is a chemical reaction. The chemicals in the colours go into the hair and pull the natural pigment out of it so it will be replaced with the new colour.

A chemical reaction is a change in which one kind of matter changes into a different kind of matter with different properties. Reactant is a substance used in a chemical reaction and a product is a substance made in a chemical reaction. Hope this is helpful! ;)
A waterfall is not a chemical reaction.
Energy can either decrease or increase during a chemical reaction depending on whether it is an exothermic reaction (energy is released) or an endothermic reaction (energy is absorbed). In an exothermic reaction, energy is released in the form of heat, and in an endothermic reaction, energy is absorbed from the surroundings.

The chemical equation sodium + chlorine → sodium chloride represents a combination reaction, where two or more substances combine to form a single product. In this case, sodium and chlorine react to form sodium chloride.
