What is the difference between O & O2 - Chemistry Stack Exchange
2017年1月10日 · O is oxygen, while O 2 is dioxygen. Examples of other oxygen molecules are: 0 3 which is ozone (trioxygen), there's O 4 that is metastable and is actaully made up of two O 2 molecules (tetraoxygen), and O 8 which is a form of pressurised solid O 2 (when you freeze O 2 to below around 55 Kelvin and pressurise to around 10 GPa (1.45e+6 psi)it ...
Why do we call O2 oxygen? - Chemistry Stack Exchange
2018年11月25日 · 1. Diamond and graphite are both arrangements of carbon atoms, each with very different properties and yet they are both pure carbon, as is a single carbon atom, of course. Likewise OX2 O X 2 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 OX2 O X 2 ...
How can carbon dioxide be converted into carbon and oxygen?
2012年8月8日 · $\begingroup$ @GregE. generating oxygen is a separate concern from CO2 removal (i.e. wouter dorgelo's 'providing astronauts with fresh oxygen' ... stated in the context of CO2 conversion to C and O2). Yes, you can generate O2 via electrolysis, but it is the concentration of CO2 and its build-up that creates a hazard for humans.
Whats the difference between 2O and O2 - Chemistry Stack …
2017年5月30日 · 2O 2 O is basically two atoms of oxygen, unbonded and separate. On the other hand, OX2 O X 2 is oxygen molecule, which is more commonly called oxygen gas. Share. Cite. Improve this answer.
Why is the first ionization enthalpy of molecular O2 less than …
2020年9月17日 · It took me some time trying to find out perfect reasons for it, because generally, bonded electrons are harder to remove than valence electrons in atoms. But indeed, not just with $\ce{O2}$, but $\ce{F2}$ ($\pu{1515 kJ mol -1}$) also has a first ionization enthalpy lesser than atomic $\ce{F}$ which is $\pu{1681 kJ mol -1}$. (I wonder why there ...
inorganic chemistry - What is the n factor of H2O2 undergoing ...
2021年2月26日 · The n-factor for $\ce{O2}$ should be $2$ as can be seen in the first half-reaction, and for $\ce{H2O}$ the n-factor should be $1$, since we have $2$ moles of $\ce{e-}$ in the second half-reaction and $2$ moles of $\ce{H2O}$, and n …
biochemistry - Why does carbon monoxide have a greater affinity …
2015年7月9日 · Oxygen, the $\ce{O2}$ molecule, is an absolutely lowsy σ donor — especially when compared to $\ce{CO}$. Its molecular orbital scheme is generally that of carbon monoxide except that it is entirely symmetric and two more electrons are included: They populate the 2π orbitals to give a triplet ground state.
Why is oxygen paramagnetic? - Chemistry Stack Exchange
2016年5月3日 · 10. To understand the paramagnetic nature of OX2 O X 2, we must first understand how atomic orbitals mix together to form molecular orbitals. In the diatomic molecules of the elements in the second period, a phenomenon known as s s - p p mixing results in an increase in the energy of the σ2pz σ 2 p z molecular orbital, and a decrease in the ...
redox - Half equations for H2O2 for its reducing and oxidising …
2014年5月1日 · 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 ...
heat - At what temperature does carbon dioxide decompose into …
Disclaimer: I am too lazy to check whether the reaction $\ce{CO2(g) <=> CO(g) + 1/2 O2(g)}$ is more favourable. There is no single tipping point where all carbon dioxide will suddenly be converted to carbon and oxygen. As you heat carbon dioxide, the percentage of oxygen present would gradually increase.
