here are various terms in chemistry like the types of Chemical Reaction, Chemical Equation, and Balancing, Types of Chemical Reactions, Redox Reaction- Rancidity and Corrosion.
We have often seen that some substances when mixed, form new substances. Like if we want to make tea, we add sugar, tea, milk, and water. On heating, it turns into tea. Likewise, if you add a spoon of curd to lukewarm milk and keep it aside for a few hours, then the whole milk turns into curd.We conclude that they thoroughly mix and form a new substance. This thorough mixing is a chemical reaction.
Chemical Reaction means thatwhen two or more substances react and form some new substance, then it is called a chemical reaction.
