Quantum chemistry and Physics textbooks usually treat the binding of the molecule in the electronic ground state by the simplest possible ansatz for the wave function: the (normalized) sum of two 1s hydrogen wave functions centered on each nucleus. This ansatz correctly reproduces the binding but is numerically unsatisfactory.
By some definitions, "organic" compounds are only required to contain carbon. However, most of them also contain hydrogen, and because it is the carbon-hydrogen bond that gives this class of compounds most of its particular chemical characteristics, carbon-hydrogen bonds are required in some definitions of the word "organic" in chemistry.

A Chem-7 is thus a vital tool when attempting to stabilize a patient. [citation needed] Calcium (Ca 2+) is often considered part of the BMP, [9] [10] though, by definition, it is not part of the CHEM-7. A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8".

Reza Valizadeh was arrested in Tehran in September, a source close to his family told his former employer Radio Farda, the Iranian branch of the US-funded Radio Free Europe/Radio Liberty (RFE/RL).
Nevertheless, muonium compounds are important test cases for quantum simulation, due to the mass difference between the antimuon and the proton, [72] and IUPAC nomenclature incorporates such hypothetical compounds as muonium chloride (MuCl) and sodium muonide (NaMu), analogous to hydrogen chloride and sodium hydride respectively.
Brady Tkachuk scored 21 seconds into overtime, lifting Ottawa to a 3-2 victory over the Bruins on Saturday night and handing a win to Linus Ullmark in his return to Boston. The 31-year-old Ullmark ...
