Colourless diboron tetrachloride (m.p. -93 °C) is a planar molecule in the solid, (similar to dinitrogen tetroxide, but in the gas phase the structure is staggered. [4] It decomposes (disproportionates) at room temperatures to give a series of monochlorides having the general formula (BCl) n, in which n may be 8, 9, 10, or 11.
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths, bond angles, torsional angles and any other geometrical parameters that determine the position of each atom. Molecular geometry influences several properties of a substance ...
Isotherms of an ideal gas for different temperatures. The curved lines are rectangular hyperbolae of the form y = a/x. They represent the relationship between pressure (on the vertical axis) and volume (on the horizontal axis) for an ideal gas at different temperatures: lines that are farther away from the origin (that is, lines that are nearer to the top right-hand corner of the diagram ...
The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called gas laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
Its determination includes a chemist's specifying the molecular geometry and, when feasible and necessary, the electronic structure of the target molecule or other solid. Molecular geometry refers to the spatial arrangement of atoms in a molecule and the chemical bonds that hold the atoms together and can be represented using structural ...
Boron triiodide can be prepared by the reaction of boron with iodine at 209.5 °C or 409.1 °F. [citation needed] It can also be prepared by reacting hydroiodic acid with boron trichloride: 3HI + BCl 3 → BI 3 + 3HCl (reaction requires high temperature) Another method is by reacting lithium borohydride with iodine.
Quizlet is a multi-national American company that provides tools for studying and learning. [1] Quizlet was founded in October 2005 by Andrew Sutherland, who at the time was a 15-year old student, [ 2 ] and released to the public in January 2007. [ 3 ]
The role of Bcl3 in solid tumors was established through the ability of Bcl3 to promote metastasis without affecting primary tumor growth or normal mammary function, within models of ErbB2-positive breast cancer. [18] Further research has uncovered the role of Bcl3 in promoting progression of other solid tumors.
