A material that can be represented by a chemical formula is a chemical compound.
What are chemical compounds?
Chemical compounds are substances made up of two or more different elements that are chemically bonded together in a specific arrangement. The elements in a compound can be either metal or nonmetal elements, or a combination of both.
Here,
A chemical compound is a substance made up of two or more different elements that are chemically bonded together. The chemical formula of a compound provides information about the types and numbers of atoms in a molecule of the compound.
For example, water is a chemical compound represented by the formula H2O, which tells us that each molecule of water contains two hydrogen atoms (H) and one oxygen atom (O) bonded together.
Chemical formulas are important tools for chemists to communicate information about the composition and structure of compounds. They allow scientists to predict how compounds will react and to design new compounds with desired properties.
