  2. Indium(III) hydroxide - Wikipedia

    en.wikipedia.org/wiki/Indium(III)_hydroxide

    Neutralizing a solution containing an In 3+ salt such as indium nitrate (In(NO 3) 3) or a solution of indium trichloride (InCl 3) gives a white precipitate that on aging forms indium(III) hydroxide. [4] [5] A thermal decomposition of freshly prepared In(OH) 3 shows the first step is the conversion of In(OH) 3 ·xH 2 O to cubic indium(III ...

  3. Direct stiffness method - Wikipedia

    en.wikipedia.org/wiki/Direct_stiffness_method

    Once the global stiffness matrix, displacement vector, and force vector have been constructed, the system can be expressed as a single matrix equation. For each degree of freedom in the structure, either the displacement or the force is known.

  4. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.

  6. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Reaction stoichiometry describes the 2:1:2 ratio of hydrogen, oxygen, and water molecules in the above equation. The molar ratio allows for conversion between moles of one substance and moles of another. For example, in the reaction 2 CH 3 OH + 3 O 2 → 2 CO 2 + 4 H 2 O. the amount of water that will be produced by the combustion of 0.27 moles ...

  8. Polarizability - Wikipedia

    en.wikipedia.org/wiki/Polarizability

    This results because of alkene's and arene's more electronegative sp 2 carbons to the alkane's less electronegative sp 3 carbons. [9] Ground state electron configuration models often describe molecular or bond polarization during chemical reactions poorly, because reactive intermediates may be excited, or be the minor, alternate structures in a ...

  9. Alcohol (chemistry) - Wikipedia

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

    When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...
