Process by which atoms or one substance are rearranged to form different substances.

Answer 1

The process by which atoms or one substance are rearranged to form different substances is called a chemical reaction. In a chemical reaction, the bonds between atoms are broken and new bonds are formed, resulting in the conversion of reactants into products. This rearrangement of atoms can involve various types of reactions, such as combination reactions, decomposition reactions, displacement reactions, and redox reactions. The overall process is governed by the principles of conservation of mass and energy.
