log 10 (K eq) has a value of zero at approx. 975 K. The implication of the change in K eq with temperature is that a gas containing CO may form elemental carbon if the mixture cools below a certain temperature. The thermodynamic activity of carbon may be calculated for a CO / CO 2 mixture by knowing the partial pressure of each species and the ...
Basic copper carbonate is a chemical compound, more properly called copper(II) carbonate hydroxide.It can be classified as a coordination polymer or a salt.It consists of copper(II) bonded to carbonate and hydroxide with formula Cu 2 (CO 3)(OH) 2.
L n M−OH + H + ⇌ L n M−OH + 2 where L n is the ligand complement on the metal M. Thus, aquo ligand is a weak acid, of comparable strength to acetic acid (pK a of about 4.8). [6] In principle but not very commonly, metal hydroxides undergo deprotonation, yielding oxo complexes: L n M−OH ⇌ L n M=O − +H +
Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.
Cobalt(II) hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Co 2+ salt. [4] For example, Co 2+ + 2 NaOH → Co(OH) 2 + 2 Na + The compound can be prepared by reacting cobalt(II) nitrate in water with a solution of triethylamine N(C 2 H 5) 3 as both the base and a complexing agent.

The mineral of the formula Cu(OH) 2 is called spertiniite. Copper(II) hydroxide is rarely found as an uncombined mineral because it slowly reacts with carbon dioxide from the atmosphere to form a basic copper(II) carbonate. Thus copper(II) hydroxide slowly acquires a dull green coating in moist air by the reaction: 2 Cu(OH) 2 + CO 2 → Cu 2 CO ...
An often studied dihydrogen complex of iron, [HFe(H 2)(dppe) 2] +.. The usual method for characterization is 1 H NMR spectroscopy.The magnitude of spin–spin coupling, J HD, is a useful indicator of the strength of the bond between the hydrogen and deuterium in HD complexes.
Cobalt(II) thiocyanate is an inorganic compound with the formula Co(SCN) 2. [1] The anhydrous compound is a coordination polymer with a layered structure. The trihydrate, Co(SCN) 2 (H 2 O) 3, is a isothiocyanate complex used in the cobalt thiocyanate test (or Scott test) for detecting cocaine. The test has been responsible for widespread false ...
