Other fields includechemists who isolate products created by living organisms and then characterize and study these products.

Products are the species formed from chemical. During a chemical reaction are transformed into products after passing through a high energy state. This process results in the consumption of the reactants. It can be reaction or mediated by catas which lower the energy of the transition state, and by solvents which provide the chemical environment necessary for the reaction to take place. When represented in chemical products are by convention drawn on the right-hand side, even in the case of reaction. The properties of products such as their energies help determine several characteristics of a chemical reaction such as whether the reaction is fine. Additionally the properties of a product can make it easier to extract and purify following a chemical reaction, especially if the product has a different matter than the reactants. Reactants are molecular materials used to create chemical reactions. The atoms aren't created or destroyed. The materials are reactive and reactants are rearranging during a chemical reaction. Here is an example of reactants: CH4 + O2. A non-example is CO2 + H2O or "energy".

Much of chemical research is focused on the sunthests and characterization of beneficial products, as well as the detection and removal of undesirable products. Synthetic chemists can be subdivided into research chemists who design new chemicals and pioneer new methods for synthesizing chemicals, as well as  process who scale up chemical production and make it safer, more environmentally sustainable, and more efficient.Other fields includechemists who isolate products created by living organisms and then characterize and study these products.

The products of a chemical reaction influence several aspects of the reaction. If the products are lower in energy than the reactants, then the reaction will give off excess energy making it an reaction. Such reactions are thermodynamically favorable and tend to happen on their own. If the kinestic of the reaction are high enough, however, then the reaction may occur too slowly to be observed, or not even occur at all. This is the case with the conversion of diamond to lower energy graphite at atmospheric pressure, in such a reaction diamond is considered metasble and will not be observed converting into graphite.

If the products are higher in chemical energy than the reactants then the reaction will require energy to be performed and is therefore an endergonic reaction. Additionally if the product is less stable than a reactant, then Leffler's assumption holds that the transition state will more closely resemble the product than the reactant.Sometimes the product will differ significantly enough from the reactant that it is easily purified following the reaction such as when a product is insoluble and precipitates out of solution while the reactants remained dissolved.

Formula

Rules for chemical formulas 

· Enter a sequence of element symbols followed by numbers to specify the amounts of desired elements (e.g., C6H6).

· Use correct case for element symbols. If correct case is not used, the formula may be ambiguous and the interpretation chosen may not be the desired one.

· Elements may be in any order.

· If only one of a given atom is desired, you may omit the number after the element symbol.

· Parentheses may be used to group atoms.

· Multiple specifications for an atom will be added. This means that CH3(CH2)4CH3 will be treated the same as C6H14.

· To specify one or more of a given atom, use a question mark (?) after the element symbol.

· To specify any number (including zero) of given element, use an asterisk (*) after the element symbol.

· To explicitly specify an ion, place the charge at the end of the formula. If the charge is greater than one the charge should be included after the + or - symbol (e.g., C60-2).

Examples of chemical formulas

C2H*F?

Species with two C, zero or more H and one or more F.

Search options (step 2)

Exactly match the specified isotopes

When checked, this option indicates that the search should match isotopes as specified in the search formula. For example, when this option is not checked a search on H2 will match species containing deuterium and tritium atoms. If this option was checked, deuterium and tritium would be excluded from the search.

Allow elements not specified in formula

When checked, this option indicates that species containing elements not specified in the formula will also be matched. For example, a search for Te2 will find all of the species which contain exactly two tellurium atoms and any number of other atoms. Checking this option alone is equivalent to the "partial formula search" previously available from this site.

Allow more atoms of elements in formula than specified

This option indicates that species containg more atoms than specified of a given element will be matched. For example, a search for with only this option checked will find all tellurium, ditellurium, tritellurium, etc.

Exclude ions from the search

When this option is checked, the search will not match ions unless a charge is explicitly indicted in the formula.

Rules for data types (step 4) 

· If one or more of the data types are checked, the search will be restricted to species which contain at least one of the data types specified.

· If none of the data types are checked, there will be no restrictions on the search.
