Doing chemical reactions is the main focus of chemistry because that's where the action is that's when something gets made, changed, or destroyed.
Students work with a series of cards (showing word descriptions, photographs or equations) related to chemical reactions that are used as energy sources or for making new materials or that are important in biological systems. Chemical reactions exothermic reactions: when one substance is brought together or mixed with another and the resulting interaction evolves or generates heat, the process is referred to as an exothermic reaction. Chemical kinetics describes the relationship between measured rates of chemical reactions and the detailed atomic and molecular mechanisms via which the observed chemical change occurs.
