Final answer:
The process of amalgamation refers to different groups coming together to form a new culture, while in chemistry, a combination or composition reaction is the merging of two or more reactants to form a single new substance.
Step-by-step explanation:
The term for the process of combining one thing with another to make them whole is known as amalgamation in social studies, and combination or composition reaction in chemistry. In combination reactions, two or more reactants merge to form a single new substance.
The general form of a combination reaction is represented by the chemical equation A+B → AB. This process is crucial in chemistry as it allows atoms to be held together by chemical bonds, and through these reactions, new substances with different compositions of elements are created, distinguishing reactants from products.
