  2. Sulfuryl chloride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_chloride

    Sulfuryl chloride is used as a source of Cl 2.Because it is a pourable liquid, it is considered more convenient than Cl 2 to dispense.. Sulfuryl chloride is used in the conversion of C−H to C−Cl adjacent to activating substituents such as carbonyls and sulfoxides: [5] [6]

  3. Stone (unit) - Wikipedia

    en.wikipedia.org/wiki/Stone_(unit)

    The stone remains widely used in the United Kingdom and Ireland for human body weight: in those countries people may commonly be said to weigh, e.g., "11 stone 4" (11 stones and 4 pounds), rather than "72 kilograms" as in most of the other countries, or "158 pounds", the conventional way of expressing the same weight in the US and in Canada. [38]

  4. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  5. Mass fraction (chemistry) - Wikipedia

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

    Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...

  6. Sulfuryl chloride fluoride - Wikipedia

    en.wikipedia.org/wiki/Sulfuryl_chloride_fluoride

    Further heating (180 °C) of potassium fluorosulfite with the sulfuryl chloride fluoride gives sulfuryl fluoride. KSO 2 F + SO 2 ClF → SO 2 F 2 + KCl + SO 2. Alternatively, sulfuryl chloride fluoride can be prepared without using gases as starting materials by treating sulfuryl chloride with ammonium fluoride or potassium fluoride in ...

  7. Stoichiometry - Wikipedia

    en.wikipedia.org/wiki/Stoichiometry

    Gas stoichiometry calculations solve for the unknown volume or mass of a gaseous product or reactant. For example, if we wanted to calculate the volume of gaseous NO 2 produced from the combustion of 100 g of NH 3, by the reaction: 4 NH 3 (g) + 7 O 2 (g) → 4 NO 2 (g) + 6 H 2 O (l) we would carry out the following calculations:

  8. Chlorosulfonyl isocyanate - Wikipedia

    en.wikipedia.org/wiki/Chlorosulfonyl_isocyanate

    CSI is prepared by treating cyanogen chloride with sulfur trioxide, the product being distilled directly from the reaction mixture. [1] SO 3 + ClCN → ClSO 2 NCO. In this transformation, both the carbon and the nitrogen termini of CN are functionalized. The structure of CSI is represented as ClS(O) 2-N=C=O.

  9. Bulk density - Wikipedia

    en.wikipedia.org/wiki/Bulk_density

    In materials science, bulk density, also called apparent density, is a material property defined as the mass of the many particles of the material divided by the bulk volume. Bulk volume is defined as the total volume the particles occupy, including particle's own volume, inter-particle void volume, and the particles' internal pore volume.
