This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
The leading term of a nonzero polynomial [,, …,], denoted by () is the monomial term of maximal order in and the leading term of = is . The ideal of leading terms , denoted by L T ( I ) {\displaystyle LT(I)} , is the ideal generated by the leading terms of every element in the ideal, that is, L T ( I ) = ( L T ( f ) ∣ f ∈ I ...
In mathematics, a monomial is, roughly speaking, a polynomial which has only one term. Two definitions of a monomial may be encountered: A monomial, also called a power product or primitive monomial, [1] is a product of powers of variables with nonnegative integer exponents, or, in other words, a product of variables, possibly with repetitions. [2]
The leading term of a polynomial is thus the term of the largest monomial (for the chosen monomial ordering). Concretely, let R be any ring of polynomials. Then the set M of the (monic) monomials in R is a basis of R , considered as a vector space over the field of the coefficients.
Then we can consider the monomial defined by α: X α = X 1 α 1 X 2 α 2 X 3 α 3.... Then m α is the symmetric function determined by X α, i.e. the sum of all monomials obtained from X α by symmetry. For a formal definition, define β ~ α to mean that the sequence β is a permutation of the sequence α and set
Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
Chemistry classifies monomers by type, and two broad classes based on the type of polymer they form. By type: natural vs synthetic, e.g. glycine vs caprolactam, respectively; polar vs nonpolar, e.g. vinyl acetate vs ethylene, respectively; cyclic vs linear, e.g. ethylene oxide vs ethylene glycol, respectively; By type of polymer they form:
The Brønsted–Lowry theory (also called proton theory of acids and bases [1]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923.
