Infobox references. Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform -like odour that can be detected at low levels.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms.
Infobox references. Silicon tetrachloride or tetrachlorosilane is the inorganic compound with the formula SiCl 4. It is a colorless volatile liquid that fumes in air. It is used to produce high purity silicon and silica for commercial applications. It is a part of the chlorosilane family.
Lead tetrachloride, also known as lead (IV) chloride, has the molecular formula PbCl 4. It is a yellow, oily liquid which is stable below 0 °C, and decomposes at 50 °C. [2] It has a tetrahedral configuration, with lead as the central atom. The Pb– Cl covalent bonds have been measured to be 247 pm and the bond energy is 243 kJ⋅mol −1.
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.
As chloroform is a volatile organic compound, [18] it dissipates readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. Its half-life in air ranges from 55 to 620 days. Biodegradation in water and soil is slow.
View/Edit Human. Chemokine (C-C motif) ligands 4 (also CCL4) previously known as macrophage inflammatory protein (MIP-1β), is a protein which in humans is encoded by the CCL4 gene. [2] CCL4 belongs to a cluster of genes located on 17q11-q21 of the chromosomal region. [3] Identification and localization of the gene on the chromosome 17 was in ...
The first solvation shell of a sodium ion dissolved in water. An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, also known as sodium chloride (NaCl), in water would be represented as Na+(aq) + Cl−(aq).
