May 15, 2016 · What are the possible term symbols for excited state oxygen with configuration $ (1\pi_u)^3$,$ (1\pi^*_g)^3$ (all other occupied orbitals are closed shell)? Based on the possible values of S and $\la...
Jan 9, 2017 · What is the difference between $\ce {O}$ and $\ce {O2}$. If C is carbon and then why $\ce {O2}$ is oxygen.
Aug 8, 2012 · $\ce {CO2}$ into $\ce {CO + O2}$ is easier, but you need a catalyst and about $\pu {1500 °C}$ as reported by Richard Van Noorden’ article “ Recycling carbon dioxide into petrol ” about the Sandia reactor, 2008-01-03 (WBM link).
Jan 20, 2019 · From the bonding energy of following bonds that I found in a Wikipedia article, I calculated the reaction energy that would be released when oxygen and hydrogen are reacted to produce water. The ph...
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 (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 …
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 higher in energy than the constituent atomic orbitals, are still negative in energy, so adding electrons to AB orbitals still lowers the energy.
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. 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.
Pure oxygen does not burn. Oxygen is a supporter of combustion, not a combustible material (fuel) itself. Combustion reactions are as follows: $$\text {combustible stuff} \ce {+ O2 -> } \text {various oxides} + \text {heat}$$ Note that nitrous oxide ($\ce {N2O}$) is also a supporter of combustion, which means that you can use it to carry out a combustion reaction without …
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!
May 1, 2014 · Is there a complete list of all the half equations for $\\ce{H2O2}$ - both oxidation and reduction, in acidic and alkaline conditions? I've looked on the internet but can't seem to find a list with ...
