  2. Water model - Wikipedia

    en.wikipedia.org/wiki/Water_model

    The charged sites may be on the atoms or on dummy sites (such as lone pairs). In most water models, the Lennard-Jones term applies only to the interaction between the oxygen atoms. The figure below shows the general shape of the 3- to 6-site water models. The exact geometric parameters (the OH distance and the HOH angle) vary depending on the ...

    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 connected to one another.

  4. Sodium fluorosilicate - Wikipedia

    en.wikipedia.org/wiki/Sodium_fluorosilicate

    Sodium fluorosilicate is used in some countries as additives for water fluoridation, opal glass raw material, ore refining, or other fluoride chemical (like sodium fluoride, magnesium silicofluoride, cryolite, aluminum fluoride) production. [5] It also is an ingredient in some ceramic cements.

    Silicon disulfide is the inorganic compound with the formula Si S 2. Like silicon dioxide , this material is polymeric , but it adopts a 1-dimensional structure quite different from the usual forms of SiO 2 .

  9. Disulfur dichloride - Wikipedia

    en.wikipedia.org/wiki/Disulfur_dichloride

    Disulfur dichloride is a yellow liquid that fumes in moist air due to reaction with water: 16 S 2 Cl 2 + 16 H 2 O → 8 SO 2 + 32 HCl + 3 S 8. It is produced by partial chlorination of elemental sulfur. The reaction proceeds at usable rates at room temperature. In the laboratory, chlorine gas is led into a flask containing elemental sulfur.
