How do classify tje chemical reactions

Answer» This is a correct answer.
Chemical reactions occur when one or more molecules change chemically. In other words, bonds break between the reactants and atoms rearrange to form new chemical bonds. These reconfigured atoms can either be a compound or just an element. The products have different chemical identities compared to the reactants. Common examples of chemical reactions include the burning of fuel, respiration, and the formation of rust. We can classify chemical reactions according to the nature of the reactants or how the products are formed. In AP Chemistry, you will encounter problems that ask you to identify and predict the products of chemical reactions. In this post, we will discuss how to classify chemical reactions in detail.
