Reactants are the starting substances that undergo a chemical change, while products are the new substances formed as a result. class A chemical reaction is when substances change into new substances with different properties. What Is A Chemical Chemical reactions always involve a change in energy. This energy is usually in the form of heat. which matter changes into a new substance or · 2Pb(NO3)2 2PbO + 4NO2 + O2 · ZnCO3 ZnO + CO2 · CuCO3 CuO + It outlines characteristics of chemical reactions, types of reactions, and includes practical examples demonstrating various reactions such as displacement, The event in which substance gets transformed permanently (Chemical changes) is called chemical reaction.
