ICSE Class 9 Answered

Dear Student,

A chemical reaction is a process in which one or more substances (reactants) are converted into one or more different substances (products) by breaking and forming chemical bonds. During a chemical reaction, the atoms in the reactants rearrange to form new substances with different chemical properties. Chemical reactions involve breaking and forming chemical bonds, resulting in the creation of new substances.
One can see chemical change happening when a chemical reaction occurs.
That means chemical change is the visible result of the transformation, while the chemical reaction is the transformation process.
However, the terms "chemical reaction" and "chemical change" are often used interchangeably.
