  2. Calcium sulfide - Wikipedia

    en.wikipedia.org/wiki/Calcium_sulfide

    Calcium sulfide is the chemical compound with the formula Ca S. This white material crystallizes in cubes like rock salt. This white material crystallizes in cubes like rock salt. CaS has been studied as a component in a process that would recycle gypsum , a product of flue-gas desulfurization .

  3. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  4. Calcium sulfite - Wikipedia

    en.wikipedia.org/wiki/Calcium_sulfite

    Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfite with the formula CaSO 3 ·x(H 2 O). Two crystalline forms are known, the hemihydrate and the tetrahydrate, respectively CaSO 3 ·½(H 2 O) and CaSO 3 ·4(H 2 O). [2] All forms are white solids. It is most notable as the product of flue-gas desulfurization.

  5. Table of specific heat capacities - Wikipedia

    en.wikipedia.org/wiki/Table_of_specific_heat...

    Note that the especially high molar values, as for paraffin, gasoline, water and ammonia, result from calculating specific heats in terms of moles of molecules. If specific heat is expressed per mole of atoms for these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limit of 25 J⋅mol ...

  6. Osmotic coefficient - Wikipedia

    en.wikipedia.org/wiki/Osmotic_coefficient

    where is the chemical potential of the pure solvent and is the chemical potential of the solvent in a solution, M A is its molar mass, x A its mole fraction, R the gas constant and T the temperature in Kelvin. [1] The latter osmotic coefficient is sometimes called the rational osmotic coefficient. The values for the two definitions are ...

  7. Calcium carbide - Wikipedia

    en.wikipedia.org/wiki/Calcium_carbide

    The pure material is colorless, while pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide), CaS (calcium sulfide), Ca 3 N 2 (calcium nitride), SiC (silicon carbide), C , etc.). In the presence of trace moisture, technical-grade calcium ...

  8. Calcium sulfate - Wikipedia

    en.wikipedia.org/wiki/Calcium_sulfate

    Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO 4 and related hydrates. In the form of γ- anhydrite (the anhydrous form), it is used as a desiccant . One particular hydrate is better known as plaster of Paris , and another occurs naturally as the mineral gypsum .

  9. Calcium oxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_oxide

    Small quantities of quicklime are used in other processes; e.g., the production of glass, calcium aluminate cement, and organic chemicals. [10] Heat: Quicklime releases thermal energy by the formation of the hydrate, calcium hydroxide, by the following equation: [11] CaO (s) + H 2 O (l) ⇌ Ca(OH) 2 (aq) (ΔH r = −63.7 kJ/mol of CaO)
