Calcium bromide is the name for compounds with the chemical formula Ca Br 2 (H 2 O) x. Individual compounds include the anhydrous material (x = 0), the hexahydrate (x = 6), and the rare dihydrate (x = 2). All are white powders that dissolve in water, and from these solutions crystallizes the hexahydrate.
LaC 2 reacts with water to form acetylene, C 2 H 2 and a mixture of complex hydrocarbons. [3] LaC 2 is a metallic conductor, in contrast to CaC 2 which is an insulator. [3] The crystal structure of LaC 2 shows that it contains C 2 units with a C-C bond length of 130.3 pm, which is longer than the C-C bond length in calcium carbide, 119.2 pm, which is close to that of ethyne.

The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Levidian CEO John Hartley shows CBS News' Tina Kraus the British company's patented LOOP system, which breaks down methane molecules into hydrogen and carbon and collects the carbon, in the form ...
The LA-2A had evolved from Lawrence's first leveling amplifier, the LA-1, which was favored by Gene Autry, and its successor, the LA-2, which had been adopted by CBS and RCA. In 1965, Lawrence sold Teletronix to Babcock Electronics of Costa Mesa, California, and in 1967 Bill Putnam 's company Studio Electronics (eventually renamed UREI ...
Lanthanum oxide is used in optical materials; often the optical glasses are doped with La 2 O 3 to improve the glass' refractive index, chemical durability, and mechanical strength. [8] 3 B 2 O 3 + La 2 O 3 → 2 La(BO 2) 3 [clarification needed] The addition of the La 2 O 3 to the glass melt leads to a higher glass transition temperature from ...
From December 2011 to December 2012, if you bought shares in companies when Nancy McKinstry joined the board, and sold them when she left, you would have a 20.1 percent return on your investment, compared to a 13.6 percent return from the S&P 500.
Because it is commonly recrystallized from chloroform, the complex is often supplied as the adduct [Pd 2 (dba) 3 ·CHCl 3]. [1] The purity of samples can be variable. [3] In [Pd 2 (dba) 3], the pair of Pd atoms are separated by 320 pm but are tied together by dba units. [4] The Pd(0) centres are bound to the alkene parts of the dba ligands.
