Final answer:
The correct term for a process where substances change and chemical bonds are altered is a 'chemical reaction'. It is represented by a chemical equation, which is balanced to show conservation of mass with the same atoms present in both reactants and products.
Step-by-step explanation:
The term that describes a situation in which one or more substances change into something new, with chemical bonds being formed or broken in the process, is a chemical reaction. During a chemical reaction, the substances that undergo the reaction, known as reactants, are transformed into new substances called products. This transformation involves the breaking and formation of chemical bonds, leading to a chemical change where the reactants become different at a molecular level. Chemical equations represent these reactions, showing reactants on the left side, the yields arrow in the middle, and products on the right side. These equations must be balanced to adhere to the conservation of mass with the same number and types of atoms on both sides.
To summarize, a chemical reaction signifies the process of transforming reactants into products, resulting in the creation of new substances. The way chemists track these reactions is through balanced chemical equations, ensuring mass is conserved throughout the reaction. Remember, the correct answer to the question is 'b) Chemical Reaction'.
