Chemical Compound Formulas

Chemical Compound Formulas

Chemistry is a science of composition of matter and transformation of its physical or chemical property. Our universe is made of matter. The matter is composed of atoms of various different chemical elements that are found in pure as well as combined form. Any substance consisting of the matter is called chemical. They occur in the form of solids, liquids or gases. It can exist as a pure substance or as a mixture. Every chemical element is represented by a unique symbol.

There are naturally occurring chemicals and artificially made chemicals. Examples of naturally occurring chemicals are as follows:

  • Solids – Rocks, plant fibers, soil, minerals such as zinc, copper, etc.
  • Liquids – Water
  • Gases – Hydrogen, nitrogen, oxygen

Artificially made chemicals have various applications. They have transformed the pharmaceuticals and food industries. Due to this the food flavoring and preservation has become easy and inexpensive.

The chemical formula is a way to represent any chemical substance using the symbol of the elements present in it. Below we have given a list of the chemical compound formulas along with the compound name, molecular weight, and molecular formula.
