If you mix something and it actually mix forming a new compound either solid or fluid, then the reaction is chemical. this can be as easy as burning a sheet of paper. The reaction is chemical and triggered by heat. The product you get is compositionwise different to the original product.
If having a glass of water and a glass of salt and you then mix the sand with the salt, then this would be a physical reaction. The salt and water mix, but does not actually form a new compound, only a mixture of the two.
Another physical reaction is melting of ice (The water is still water even though it is a solid as in ice.)
