How is a chemical reaction different from and a physical reaction? - Answer- A physical change is reversible, a chemical change is not. For example, the freezing of water would be a physical change because it can be reversed, whereas the burning of wood is a chemical change - you can't 'unburn' it What is the difference between an element, a compound, and a mixture? - Answer- An element is made up only one kind of atom, and cannot be broken down into simpler substances by chemical reaction...
