When you leave bread in the oven too long, it turns dark and smells different and no matter what you do, you cannot get the original bread back. That is a chemical reaction: a transformation so complete that entirely new substances are formed. But how do you know a chemical reaction has happened? And what separates a true chemical change from something as simple as melting ice? Today you explore the Concept of Chemical Reactions what they are, how to recognise them, and why they matter in every corner of science and daily life. Chemistry is always reacting now you learn to see it!
