WebMethanol, CH3-OH, is a colorless, fairly volatile liquid with a faintly sweet pungent odor, similar, but somewhat milder and sweeter than ethanol . Methanol is toxic, and may cause blindness. The vapors are slightly … WebFeb 2, 2024 · The standard enthalpy of formation of any element in its standard state is zero by definition. For example, although oxygen can exist as ozone (O 3 ), atomic oxygen (O), and molecular oxygen (O 2 ), O 2 is the most stable form at 1 atm pressure and 25°C. Similarly, hydrogen is H 2 (g), not atomic hydrogen (H).
WebFor example, the bond energy of the pure covalent H–H bond, D H–H, is 436 kJ per mole of H–H bonds broken: H 2 ( g) 2 H ( g) D H−H = Δ H ° = 436 kJ. Molecules with three or more atoms have two or more bonds. The sum of all bond energies in such a molecule is equal to the standard enthalpy change for the endothermic reaction that ...
