WebBeryllium hydroxide has the formula Be (OH)2 and the molecular weight of 43.0268 g/mol. A more likely formula is Be (OH) + OH −. It can be prepared by reacting the oxide with water: BeO + H2O ⇒ Be (OH)2 It is a white solid with a density of 1.92 g/cm 3. Its heat of formation, Δ Hf, is –20.98 kJ/g and its specific heat capacity, Cp, is 1.443 J/K. Web29 aug. 2024 · But if all lithium was formed by cosmic rays, none could have been formed by the Big Bang. Since any Big Bang explosion would definitely have created a minimum amount of lithium, this is more evidence that the Big Bang never happened. Thus boron and beryllium abundances give clues to the history of the galaxy and indeed of the universe.
