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 ...
E. J. Bowen (1898–1980), English physical chemist; Humphry Bowen (1929–2001), English analytical chemist; Paul D. Boyer (1918–2018), American biochemist, 1997 Nobel Prize in Chemistry; Robert Boyer (1909–1989), American Chemist, employee of Henry Ford focus on soybean use; Robert Boyle (1627–1691), Irish-English pioneer of modern ...
Some chemists with relatively higher experience might change jobs or job position to become a manager of a chemistry-related enterprise, a supervisor, an entrepreneur or a chemistry consultant. Other chemists choose to combine their education and experience as a chemist with a distinct credential to provide different services (e.g., forensic ...
AlCl 2<F: aluminium chloride fluoride: 22395-91-1 AlClO: aluminium chloride oxide: 13596-11-7 AlCl 2 H: dichloroalumane: 16603-84-2 AlCl 3: aluminium chloride: 16603-84-2 AlCl 2 F: aluminium chloride fluoride: 13497-96-6 AlCl 3: aluminium trichloride: 7446-70-0 AlCl 4 Cs: aluminium caesium tetrachloride: 17992-03-9 AlCl 4 K: potassium ...
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
where k f is the rate constant for the forward reaction and k b is the rate constant for the backward reaction and the square brackets, […], denote concentration. If only A is present at the beginning, time t = 0, with a concentration [A] 0, the sum of the two concentrations, [A] t and [B] t, at time t, will be equal to [A] 0.
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
