Identifying physical and chemical changes
In a chemical change the properties of the new substances are different from the original, the particles are different and the number of particles can change While the distinction between physical and chemical change is a useful one it should be seen as more of a continuum Chemical reactions can be reversed but this can be difficult in practice...
