- What is the difference between O O2 - Chemistry Stack Exchange
What is the difference between $\ce {O}$ and $\ce {O2}$ If C is carbon and then why $\ce {O2}$ is oxygen
- Whats the difference between 2O and O2 [duplicate]
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!
- Why is oxygen paramagnetic? - Chemistry Stack Exchange
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?
- 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 gaseous water: $$\ce {2H2 (g) + O2 (g) -> 2H2O (g)}\qquad\Delta H^\circ = -484\ \mathrm {kJ}$$ (By way of comparison, the corresponding value for liquid water is about
- orbitals - What is the origin of the differences between the MO schemes . . .
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 (combination) can occur lowering the energy of the σ (2s) and σ* (2s) and increasing the energy of the σ (2p) and σ* (2p) molecular orbitals By moving towards right in a period, the s orbital gets more
- Why is oxygen an oxidizing agent? - Chemistry Stack Exchange
-2 Oxygen (O2) generally exists as diradicals i e each oxygen bonded to each other through single bonds and the remaining two electrons remains on each oxygen atoms as radicals So this structural feature makes oxygen act as a strong oxidizing agent
- Why do we call O2 oxygen? - Chemistry Stack Exchange
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 Like Humpty Dumpty in Alice in Wonderland, "a word means what [we] choose it to mean" and often we have to add modifiers or alternate terms to avoid ambiguity
- Why is oxygen more stable than oxygen dication?
According to molecular orbital theory (MOT), OX2X2+ O X 2 X 2 + has a greater bond order than OX2 O X 2 and two less antibonding electrons So why is molecular oxygen OX2 O X 2 more stable than the molecular ion OX2X2+? O X 2 X 2 +? One possible reason that comes to mind is that the antibonding (AB) orbitals, although higher in energy than the constituent atomic orbitals, are still negative in
