In their groups, students may discuss and analyze problems and their answers to questions that are crafted. As they formulate their ideas, they may share their understanding and discoveries with other groups. Rather than having the instructor begin class by defining terms and laying out concepts, students work actively to understand the content.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
The game consists of a deck of 121 cards. [1] Each card depicts a chemical as "monster-themed caricature". [2] A card is one of three types: [1] A further expansion, Elementeo Chemistry Card Game: Legacy Edition, released in 2023, introduces advanced gameplay mechanics, additional element cards like terbium and ytterbium, and expanded alchemy options.

HLA-DM is a molecular chaperone [5] that works in lysosomes and endosomes in cells of the immune system. It works in APCs like macrophages, dendritic cells, and B cells [6] by interacting with MHC class II molecules. [7] HLA-DM protects the MHC class II molecules from breaking down, and regulates which proteins or peptides bind to them as well. [5]
PhET Interactive Simulations is part of the University of Colorado Boulder which is a member of the Association of American Universities. [10] The team changes over time and has about 16 members consisting of professors, post-doctoral students, researchers, education specialists, software engineers (sometimes contractors), educators, and administrative assistants.

In the organometallic chemistry reaction of nucleophilic abstraction, Me 3 NO is employed as a decarbonylation agent according to the following stoichiometry: M(CO) n + Me 3 NO + L → M(CO) n−1 L + Me 3 N + CO 2. This reaction is used to decomplex organic ligands from metals, e.g. from (diene)Fe(CO) 3. [13]
