E. Essay

38. Compounds exist in enormous numbers. Common names do not describe the chemical composition of a compound. They may relate to a physical or chemical property, but usually do not reveal what elements are in the compound. The systemic method that was adopted not only tells what atoms are in the compound, but gives information on the ratio in which they have combined to form the compound and permits efficient and effective communication between chemists.
