Naming Chemical Formulas Chemical Nomenclature There are over 19 million known chemical substances. Without some type of system‚ naming these substances would be hopelessly complicated. The system used in naming substances is called chemical nomenclature. There are two major divisions to the International Union of Pure and Applied Chemistry (IUPAC) system: inorganic nomenclature organic nomenclature Organic compounds contain carbon‚ usually in combination with hydrogen‚ oxygen‚ nitrogen

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a

eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species combining
