  1. What is the difference between O & O2 - Chemistry Stack Exchange

    Jan 9, 2017 · What is the difference between $\ce {O}$ and $\ce {O2}$. If C is carbon and then why $\ce {O2}$ is oxygen.

  2. Whats the difference between 2O and O2 [duplicate]

    May 30, 2017 · I just saw something in a chemistry lesson what got me confused. What is the difference between $\\ce{2O}$ and $\\ce{O2}$? Thanks for the help!

  3. Why do we call O2 oxygen? - Chemistry Stack Exchange

    Nov 25, 2018 · Likewise $\ce {O2}$ is as much oxygen as atomic oxygen is. The only complication is that what we habitually think of as oxygen is oxygen as a gas comprised of …

  4. orbitals - What is the origin of the differences between the MO …

    Jul 18, 2014 · This phenomenon is explained by s-p mixing. All the elements in the second period before oxygen have the difference in energy between the 2s and 2p orbital small enough, so …

  5. Why is oxygen paramagnetic? - Chemistry Stack Exchange

    May 3, 2016 · Paramagnetic molecules are molecules that have single electrons. When I draw the lewis structure of $\\ce{O2}$, it appears to be a diamagnetic structure. What makes it …

  6. What form of energy is produced by 2H2 + O2 -> 2H2O reaction?

    Dec 10, 2022 · Answer 1 does not describe the environment in my post. Thermodynamics says nothing about how the energy of chemical bonds is converted to the kinetic energy of H2O …

  7. stability - Why is O2 a biradical? - Chemistry Stack Exchange

    And finally there is $\ce {O#O}$ where both oxygens are positively charged and are free radicals. Why are both positively charged? It is because 3 bonds already to oxygen means 1 lone pair …

  8. Enthalpy of formation of O2 - Chemistry Stack Exchange

    Apr 13, 2025 · The enthalpy of formation of O2 is zero at any particular temperature. The element is already in its ''standard state'' . Also please note that as per IUPAC, there is no standard …

  9. Is the reaction 2 Hg + O2 → 2HgO a reversible reaction?

    Oct 16, 2024 · Are the relative importance of $\ce {2 Hg + O2 -> 2HgO}$ and $\ce {2HgO -> 2 Hg + O2}$ dependent of the temperature ? If so (yes), what is the fundamental reason of the …

  10. What is the LUMO and HOMO in and O2 diatomic

    Dec 11, 2021 · In the typical way these terms are used, the LUMO can't be the same as the HOMO. Since each of the pi spatial orbitals already have one electron, they are not …
