  2. Potassium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Potassium_hydroxide

    About 112 g of KOH dissolve in 100 mL water at room temperature, which contrasts with 100 g/100 mL for NaOH. [14] Thus on a molar basis, KOH is slightly more soluble than NaOH. Lower molecular-weight alcohols such as methanol, ethanol, and propanols are also excellent solvents. They participate in an acid-base equilibrium.

  3. Molecular model - Wikipedia

    en.wikipedia.org/wiki/Molecular_model

    The creation of mathematical models of molecular properties and behavior is referred to as molecular modeling, and their graphical depiction is referred to as molecular graphics. The term, "molecular model" refer to systems that contain one or more explicit atoms (although solvent atoms may be represented implicitly) and where nuclear structure ...

  4. Molecular modelling - Wikipedia

    en.wikipedia.org/wiki/Molecular_modelling

    Molecular modelling encompasses all methods, theoretical and computational, used to model or mimic the behaviour of molecules. [1] The methods are used in the fields of computational chemistry, drug design, computational biology and materials science to study molecular systems ranging from small chemical systems to large biological molecules and material assemblies.

  5. Potassium ozonide - Wikipedia

    en.wikipedia.org/wiki/Potassium_ozonide

    6 koh + 4 o 3 → 4 ko 3 + 2 koh(h 2 o) + o 2 The compound is metastable, and will decompose to potassium superoxide and oxygen , especially if there is any water in the atmosphere. Long-term storage in very dry atmosphere is possible below around 0 °C.

  6. Sulfur trioxide - Wikipedia

    en.wikipedia.org/wiki/Sulfur_trioxide

    The molecule SO 3 is trigonal planar.As predicted by VSEPR theory, its structure belongs to the D 3h point group.The sulfur atom has an oxidation state of +6 and may be assigned a formal charge value as low as 0 (if all three sulfur-oxygen bonds are assumed to be double bonds) or as high as +2 (if the Octet Rule is assumed). [7]

  7. Molecular biology - Wikipedia

    en.wikipedia.org/wiki/Molecular_biology

    Molecular biology is the study of the molecular underpinnings of the biological phenomena, focusing on molecular synthesis, modification, mechanisms and interactions. Biochemistry is the study of the chemical substances and vital processes occurring in living organisms .

  8. Space-filling model - Wikipedia

    en.wikipedia.org/wiki/Space-filling_model

    A space-filling model of n-octane, the straight chain (normal) hydrocarbon composed of 8 carbons and 18 hydrogens, formulae: CH 3 CH 2 (CH 2) 4 CH 2 CH 3 or C 8 H 18.Note, the representative shown is of a single conformational "pose" of a population of molecules, which, because of low Gibbs energy barriers to rotation about its carbon-carbon bonds (giving the carbon "chain" great flexibility ...

  9. Reactive oxygen species - Wikipedia

    en.wikipedia.org/wiki/Reactive_oxygen_species

    In chemistry and biology, reactive oxygen species (ROS) are highly reactive chemicals formed from diatomic oxygen (O 2), water, and hydrogen peroxide. Some prominent ROS are hydroperoxide (H 2 O 2), superoxide (O 2 −), [1] hydroxyl radical (OH.), and singlet oxygen(1 O 2). [2] ROS are pervasive because they are readily produced from O 2 ...
