  2. Molecular model - Wikipedia

    en.wikipedia.org/wiki/Molecular_model

    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 is neglected. The electronic structure is often also omitted unless it is necessary in illustrating the function of the molecule being modeled.

  3. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    Hydrogen chloride is produced by combining chlorine and hydrogen: Cl 2 + H 2 → 2 HCl. As the reaction is exothermic, the installation is called an HCl oven or HCl burner. The resulting hydrogen chloride gas is absorbed in deionized water, resulting in chemically pure hydrochloric acid. This reaction can give a very pure product, e.g. for use ...

  4. CPK coloring - Wikipedia

    en.wikipedia.org/wiki/CPK_coloring

    Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.

  5. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrogen chloride can be generated in many ways, and thus several precursors to hydrochloric acid exist. The large-scale production of hydrochloric acid is almost always integrated with the industrial scale production of other chemicals , such as in the chloralkali process which produces hydroxide , hydrogen, and chlorine, the latter of which ...

  7. Ball-and-stick model - Wikipedia

    en.wikipedia.org/wiki/Ball-and-stick_model

    A plastic ball-and-stick model of proline. In chemistry, the ball-and-stick model is a molecular model of a chemical substance which displays both the three-dimensional position of the atoms and the bonds between them. [1] The atoms are typically represented by spheres, connected by rods which represent the bonds.

  8. Conjugate (acid-base theory) - Wikipedia

    en.wikipedia.org/wiki/Conjugate_(acid-base_theory)

    A conjugate acid, within the Brønsted–Lowry acid–base theory, is a chemical compound formed when an acid gives a proton (H +) to a base—in other words, it is a base with a hydrogen ion added to it, as it loses a hydrogen ion in the reverse reaction.

  9. Chlorosulfuric acid - Wikipedia

    en.wikipedia.org/wiki/Chlorosulfuric_acid

    It is an intermediate, chemically and conceptually, between sulfuryl chloride (SO 2 Cl 2) and sulfuric acid (H 2 SO 4). [6] The compound is rarely obtained pure. Upon standing with excess sulfur trioxide, it decomposes to pyrosulfuryl chlorides: [7] 2 ClSO 3 H + SO 3 → H 2 SO 4 + S 2 O 5 Cl 2
