  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. 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 …

  3. 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 …

  4. 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 …

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

    Dec 11, 2021 · In the molecular orbital (MO) diagram for the O2 O 2 diatomic, the 2π∗g 2 π g ∗ contains two unpaired electrons. This is certainly the HOMO, as it is the highest molecular …

  6. 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 …

  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. How to find the infrared absorption spectrum of O2 and N2?

    Apr 17, 2024 · There is a good reason for not being able to find the mid-IR absorption spectra of nitrogen and oxygen. Their vibrations are infrared inactive. Infrared absorption peaks are …

  9. combustion - Why are there two measurements for O2 …

    Jan 6, 2025 · Why is oxygen concentration in flue gases (biomass combustion, recovery boilers) reported in two forms: dry flue gases and wet flue gases? This raises several questions for …

  10. electrochemistry - Why is the water reduction of oxygen favored in ...

    $\ce {O2 + 2e^- -> HOOH}$ 2) From the above we can deduce that water is the product; water is pretty stable in either acidic or basic medium - i.e. it won't react to a large extent with either …
