What Causes A Chemical Reaction?

Chemical reactions are when two or more materials combine to make a new material! The two materials usually react with each other, producing that new material. This happens when molecular and atomic bonds are broken apart or connected. A great example is when you mix baking soda and vinegar to make Carbon dioxide gas! There are a few ways to tell if something is a chemical reactions. One is that there is heat produced. Many chemical reactions result in an increase of heat. Another way is to observe the color. Materials can change color if in a chemical reaction. Also, look for bubbles or gas produced. You may even smell something. There might also be precipitate, or a leftover object after the reaction. Chemical changes happen all around us! Remember, chemical reactions can’t be reversed because they are a permanent change. Always be careful when handling chemicals!!
