Why do you need to know the chemical properties of substances? Support your answer with examples.

Chemical properties – properties of substances (chemical elements, simple substances and chemical compounds) related to chemical processes, that is, manifested in the process of a chemical reaction and affecting it.
Chemical properties include the ability to react with other substances and the ability to degrade.
This distinction is especially important in biochemistry, for example, the ability of a protein to react with other biologically active substances may depend on how it is folded.
This property is also important when storing drugs. After all, if stored improperly, the drug loses its properties, or it can completely harm human health.
