How does h2 differ from 2h
WebAug 24, 2024 · The two electrons enter an orbital whose energy is lower than that of the parent atomic orbitals, so the H 2 molecule is more stable than the two isolated hydrogen atoms. Thus molecular orbital theory correctly predicts that H 2 is a stable molecule. WebSep 19, 2024 · overall: Zn ( s) + 2H + ( aq) → Zn2 + ( aq) + H2 ( g) We then use Equation 20.4.2 to calculate the cell potential. E°cell = E°cathode − E°anode = 0.76 V. Although the reaction at the anode is an oxidation, by convention its tabulated E° value is reported as a reduction potential.
