  2. Ringer's lactate solution - Wikipedia

    en.wikipedia.org/wiki/Ringer's_lactate_solution

    Ringer's lactate solution (RL), also known as sodium lactate solution, Lactated Ringer's (LR), and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water. [1] It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure. [2]

  3. List of chemistry mnemonics - Wikipedia

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics. This article contains the list of certain mnemonics in chemistry.

  4. Chemical purity - Wikipedia

    en.wikipedia.org/wiki/Chemical_purity

    ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses. Reagent grade is almost as stringent as the ACS grade.

  5. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    This method is most useful when there are only two reactants. One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess and A is the limiting reagent.

  6. Polypropylene glycol - Wikipedia

    en.wikipedia.org/wiki/Polypropylene_glycol

    Polypropylene glycol is produced by ring-opening polymerization of propylene oxide.The initiator is an alcohol and the catalyst a base, usually potassium hydroxide.When the initiator is ethylene glycol or water the polymer is linear.

  7. Chemical equation - Wikipedia

    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

    The series has some stark differences from the book on which it's based, and some of those departures are likely to have bigger impacts on the story than others.

  9. Yield (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Yield_(chemistry)

    The stoichiometry of a chemical reaction is based on chemical formulas and equations that provide the quantitative relation between the number of moles of various products and reactants, including yields. [8] Stoichiometric equations are used to determine the limiting reagent or reactant—the reactant that is completely consumed in a reaction ...
