WebThe mixture was heated to the boiling point at 90 °C for four hours until a clear, uniform solution of selenic acid (VI) and MEOS was formed in a water-alcoholic solution. After cooling, the mixture was neutralized to pH 7.0 with 1 M sodium hydroxide and supplemented with water to the weight of 507 g. Web27 feb. 2024 · To boil 1 kg of water we need 2.3 x 106 J. Each hydrogen bond requires an input of 0.2 eV to break it. Converting that to Joules we get (0.2 eV) x (1.6 x 10-19 J / 1 eV) = 0.32 x 10-19 J per hydrogen bond. So if all our energy of boiling is breaking hydrogen bonds, we must be breaking N = (2.3 x 106 J) / (0.32 x 10-19 J/bond) ~ 7 x 1025 bonds. 5.
