Be: Bé degree (°Bé) is a method for indicating the concentration of a solution. By immersing the Baume hydrometer in the solution to be measured, the value obtained is called the Baume degree; once the Baume degree of a solution is known, its mass percentage concentration can be found in the corresponding reference table. It is widely used in industrial production. There are two types of Baume hydrometers: the light type and the heavy type. The former is used to measure liquids that are lighter than water, while the latter is used to measure liquids that are heavier than water. Bh is not clear what it refers to; it might mean Bake Hardening Steel. The number that follows indicates the material’s minimum yield strength.
The name of the chemical element Bohrium: It was named in honor of Niels Bohr. Element description: A radioactive synthetic metallic element. Element source: Thallium can be produced by bombarding bismuth-204 atoms with chromium-54. Element usage: It has no practical use. Atomic number: 107 Element symbol: Bh * Chinese name for the element: Mbo English name for the element: Bohrium Relative atomic mass: Number of protons in the nucleus: 107 Number of electrons outside the nucleus: 107 Nuclear charge: 107 Proton mass: 1.79011E-25 Relative proton mass: 107.749 Period to which it belongs: 7 Group number: VIIB Molecular weight: 214 Electron configuration: 2,8,8,8,8,8,8,8,8,8,8,2 Person who discovered it: Dubna Institute Time and place of discovery: 1976, Soviet Union Element symbol: Bh English name: Bohrium Chinese name: Mbo Relative atomic mass: 148 Common oxidation state: +4 Electronegativity: 0 Outer electron configuration: 2,8,18,32,32,13,2 Isotopes and radioisotopes: Bh-261, Bh-262, Bh-262m Electron affinity: 0 KJ·mol-1 First ionization energy: 0 KJ·mol-1 Second ionization energy: 0 KJ·mol-1 Third ionization energy: 0 KJ·mol-1 Density of the pure element: 0 g/cm3 Melting point of the pure element: 0 ℃ Boiling point of the pure element: 0 ℃ Atomic radius: 0 ångströms Ionic radius: ångströms Covalent radius: 0 ångströms Common compounds: Person who discovered them: Frolov Time of discovery: 1976 Place of discovery: Germany Or BH as an abbreviation: Bill of health. BH = Brinell hardness; it’s likely referring to Brinell hardness, but I’m not sure. I searched on Baidu: lol
It is a unit: Bohr, a common unit for compounds.
We use Asahi Kasei electrolyzers; I’m not sure how to calculate the voltage efficiency. What data is needed, and is it related to the model of the electrolyzer?
