  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. 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. Why are some molecules unable to absorb infrared radiation?

    Apr 29, 2017 · Methane $\\ce{CH4}$ is symmetrical and non polar, and so is oxygen $\\ce{O2}$. But $\\ce{O2}$ doesn't absorb IR. Why is that? People say that if a molecule can change its …

  6. Why is oxygen more stable than oxygen dication?

    Feb 19, 2021 · So why is molecular oxygen $\ce {O2}$ more stable than the molecular ion $\ce {O2^2+}?$ One possible reason that comes to mind is that the antibonding (AB) orbitals, …

  7. Why is oxygen an oxidizing agent? - Chemistry Stack Exchange

    Feb 16, 2018 · Why are diatomic oxygen molecules STILL reactive especially with metallic elements like sodium and copper even at room temperature? You would think that since the …

  8. 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 …

  9. Enthalpy of the reaction between hydrogen and oxygen

    In this case, the enthalpy of $484\ \mathrm {kJ}$ is released when $2\ \mathrm {mol}$ of hydrogen gas react with $1\ \mathrm {mol}$ of oxygen gas to form $2\ \mathrm {mol}$ of …

  10. biochemistry - Why does carbon monoxide have a greater affinity …

    Jul 9, 2015 · Although CO has a much greater affinity for a ferrous heme than does O2 (by a factor of about 25,000), the affinity of CO for deoxyhemoglobin is only about 200 times greater …
