A chemical compound is formed as a result of a chemical change and in this process different types of energies such as heat, electrical energy, radiation etc. are either absorbed or evolved. The process involving a chemical change is called a chemical reaction. Chemical change – one or more new substances with new physical and chemical properties are formed. Example: Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) (Blue) (Green) Here, when copper sulphate reacts with iron, two new ...
