Chemists have used the word chemical to describe several compounds since the 1970s, and it’s only in recent years that scientists have been able to come up with a name for it.
In this video, MIT professor and Nobel laureate Jens Wunderlich describes the history of chemical meanings.
The word chemical is used in the sense of a molecule or chemical reaction, and this is what happens when you use it to describe an organic compound.
The definition of chemical has evolved over time.
For example, the word gas was originally a synonym for a mixture of water and oxygen, but has since been changed to gas.
Chemical elements are also more commonly used in other senses.
Chemicals are used to refer to chemicals with a chemical structure, such as the molecule benzene or the molecule carbon.
There are many ways that chemical elements can be used in language.
Chemists usually use the word to refer only to compounds that have an identifiable chemical structure.
They can also refer to compounds whose chemical structure has been studied, such like the chemical structure of benzene.
Chemical meaning can be defined in several ways.
For instance, chemical meaning can refer to any chemical substance.
For more information on the meaning of chemical elements, see Chemical Meaning.
Chemical words can be grouped according to their chemical meanings, or they can be restricted to the same chemical structure as their chemical names.
The term chemical meaning has also evolved over the years.
Chemist John Deacon, a member of the Massachusetts Institute of Technology’s department of chemistry, used the term chemical to refer not just to chemical elements but also to compounds made from them.
The Chemical Society of America also recognizes chemical meanings for various compounds.
Chemical meanings can be very useful, but they can also be confusing, as they refer to different molecules with the same chemistry.
For this reason, scientists have also developed more complex names for chemical elements.
