Germanium tetrafluoride is a noncombustible, strongly fuming gas with a garlic-like odor. It reacts with water to form hydrofluoric acid and germanium dioxide. Decomposition occurs above 1000 °C. [5] Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. [6]
Tin(IV) fluoride is a chemical compound of tin and fluorine with the chemical formula SnF 4 and is a white solid with a melting point above 700 °C. [1] SnF 4 can be prepared by the reaction of tin metal with fluorine gas: [2] Sn + 2F 2 → SnF 4. However, a passivating metal fluoride layer will be created and the surface will eventually become ...
Xenon tetrafluoride is a colorless crystalline solid that sublimes at 117 °C. Its structure was determined by both NMR spectroscopy and X-ray crystallography in 1963. [ 6 ] [ 7 ] The structure is square planar , as has been confirmed by neutron diffraction studies. [ 8 ]
Spartan is a molecular modelling and computational chemistry application from Wavefunction. [2] It contains code for molecular mechanics , semi-empirical methods , ab initio models , [ 3 ] density functional models , [ 4 ] post-Hartree–Fock models, [ 5 ] and thermochemical recipes including G3(MP2) [ 6 ] and T1.

Like many others who found themselves working remotely, Linette Miller, 59, noticed that she had become sedentary. “It suddenly dawned on me how little activity I get every day,” Miller, from ...
The Lions already became the first NFL team to clinch a playoff spot in Week 14, and they could be followed by the Eagles and Vikings on Sunday.
Plus, they’re rich in fiber for better digestion and a healthier heart. And speaking of heart health, they’re naturally low in saturated fat, so they won’t raise your cholesterol.
The model assigned E and C parameters to many Lewis acids and bases. Each acid is characterized by an E A and a C A. Each base is likewise characterized by its own E B and C B. The E and C parameters refer, respectively, to the electrostatic and covalent contributions to the strength of the bonds that the acid and base will form. The equation is
