The Regents exams are administered in January, June, and August. The Chemistry, Earth Science, and Physics examinations are currently labeled as part of the "Physical Setting" of science. However, all of the exams will soon be renamed and modified in realignment to the NYS Next Generation Learning Standards (NGLS).
In chemistry, a reagent ( / riˈeɪdʒənt / ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. [ 1] The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. [ 1]
an organic acid; is one of the simplest carboxylic acids. Acetone. an organic compound; simplest example of the ketones. Acetylene. a hydrocarbon and the simplest alkyne; widely used as a fuel and chemical building block. Ammonia. inorganic; the precursor to most nitrogen-containing compounds; used to make fertilizer. Ammonium hydroxide.
Reagent Chemicals. Reagent Chemicals[ a] is a publication of the American Chemical Society (ACS) Committee on Analytical Reagents, [ 1] detailing standards of purity for over four hundred of the most widely used chemicals in laboratory analyses and chemical research. Chemicals that meet this standard may be sold as "ACS Reagent Grade" materials.

These reagents were discovered by Henry Gilman and coworkers. [ 3] Lithium dimethylcopper (CH 3) 2 CuLi can be prepared by adding copper (I) iodide to methyllithium in tetrahydrofuran at −78 °C. In the reaction depicted below, [ 4] the Gilman reagent is a methylating reagent reacting with an alkyne in a conjugate addition, and the negative ...
Limiting reagent. The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. [ 1][ 2] The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in ...
