Potassium chromate is the inorganic compound with the formula K 2 CrO 4. This yellow solid is the potassium salt of the chromate anion. It is a common laboratory chemical, whereas sodium chromate is important industrially.
For example, at 2,200 °C (2,470 K; 3,990 °F) about three percent of all H 2 O are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H 2, O, O 2, and OH. Other reaction products like H 2 O 2 or HO 2 remain minor. At the very high temperature of 3,000 °C (3,270 K; 5,430 °F) more than half of the water molecules are ...
Structure of [Co 2 (OH 2) 10] 4+ color code: red = O, white = H, blue = Co. In the binuclear ion [Co 2 (OH 2) 10] 4+ each bridging water molecule donates one pair of electrons to one cobalt ion and another pair to the other cobalt ion. The Co-O (bridging) bond lengths are 213 picometers, and the Co-O (terminal) bond lengths are 10 pm shorter.
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.
Lara Trump, President-elect Donald Trump's daughter-in-law who served as co-chair of the Republican National Convention during the 2024 election, said Saturday she is removing her name from ...

From January 2008 to December 2012, if you bought shares in companies when James S. Crown joined the board, and sold them when he left, you would have a -2.5 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
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. For example, J HD is 43.2 Hz in HD but 33.5 Hz in W(HD)(CO) 3 (P i Pr ...
