  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 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, although …

  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 that s-p mixing …

  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 paramagnetic?

  6. 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 $\ce {O2}$ molecules. …

  7. How to determine whether a given compound is paramagnetic or ...

    Jun 27, 2016 · Paramagnetism is a consequence of having one or more un-paired electrons in the outer electronic configuration. e.g. O2, and NO. Most phys. chem. or inorganic chemistry textbooks will …

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

    Dec 10, 2022 · 0 Thermal energy is released from the reaction $\ce {2H2 + O2 -> 2H2O}$. Before the reaction takes place the system of $\ce {H2}$ and $\ce {O2}$ molecules are in a metastable state: …

  9. What explains the relative order of melting and boiling of oxygen and ...

    Jan 26, 2024 · 5 Why is the melting point of nitrogen ($\ce {N2}$) greater than that of oxygen ($\ce {O2}$)? After all, both are non-polar, and $\ce {O2}$ has more electrons than $\ce {N2}$. In addition, …

  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 hydronium or …
