Final answer:
In chemical reactions, we have distinct groups of compounds that react and new compounds that are produced. Chemists categorize reactions to predict outcomes and understand that reactions involve breaking and forming bonds without destroying atoms.
Step-by-step explanation:
In all chemical reactions, we have (1) distinct groups of compounds. The compounds that are (2) reacting with each other and the compounds that are (3) produced from that interaction or reaction.
To cope with the vast diversity of chemical reactions, chemists categorize reactions into types. This helps to predict which compounds will react with one another and what products will form. Understanding the basic types of chemical reactions is crucial for predicting the outcomes of reactions. For example, molecules of elements contain only one kind of atom whereas molecules of compounds contain two or more types of atoms chemically bonded together, and through reactions, these bonds can break and reform to create new substances, embodying the law of conservation of mass.
Chemical reactions are the processes that either break or form the bonds between atoms of molecules and compounds. For instance, combining two hydrogen atoms with one oxygen atom yields water, a compound with properties distinct from either hydrogen or oxygen alone.
