Substance Search Welcome to Common Chemistry ™ from Chemical Abstracts Service (CAS) a web resource that contains CAS Registry Numbers for approximately 7 900 chemicals of widespread general public interest Common Chemistry is helpful to non-chemists who know either a name or CAS Registry Number of a common chemical and want to pair both pieces of information

Believe it or not some chemists do have a sense of humour and this page is a testament to that Here we'll show you some real molecules that have unusual ridiculous or downright silly names If you know of any other potential candidates for this page please let me know People from all over the world have sent me so many contributions to this page that I've now had to split it into four

When iron is exposed to oxygen gas in the air this forms What is a rust? 300 This is how a chemical reaction is written using symbols instead of words What is a chemical equation 300 When balancing a chemical equation you NEVER change this small number that goes after the chemical symbol What is the subscript? 300 This is needed in photosynthesis in order for CO 2 to interact H 2 O

the symbol (aq) signifies that the ions are in aqueous solution Calculation of the air-to-fuel mass ratio (A/F ratio) employed by combustion engineers is complicated by the differing molar masses of dioxygen and air For methane combustion the A/F ratio works out to about 17 2 (For the detailed calculation see here) A/F ratios which exceed the stoichiometric values are said to be

List of chemical symbols Most chemical elements are represented symbolically by two letters generally the first two in their name In some cases the first letter together with some other letter from their name was used particularly when their first two letters had already been allocated to another element

Elutriation is the process of flowing air over particles Lighter particles are picked up by the air stream while heavier ones remain in place Usage Examples Forced-circulation crystallizers are commonly used to produce salts and chemicals in industry The forced-circulation crystallizer shown on the left is used to produce sodium sulfate while that on the right is used in the agricultural

The chemical equation for the combustion of hydrogen is 2H 2 + O 2 → 2H 2 O During hydrogen combustion the heat from burning makes hydrogen chemically react with oxygen gas O 2 in the air to form water In this reaction two molecules of hydrogen gas H 2 react with one molecule of O 2 to form two molecules of water H 2 O A significant amount of energy in the form of heat is

Chemical reactions also called chemical changes refer to processes that alter chemical compounds making new substances out of one or more old substances To put that another way the atoms of a substance are rearranged when a chemical change takes place In contrast to physical changes chemical changes cannot usually be reversed unless an equivalent chemical reaction takes place
