- What is the difference between O O2 - Chemistry Stack Exchange
$\ce O$ is a free oxygen atom and $\ce{O2}$ is two oxygen atoms chemically bound to form an oxygen molecule There is no common analogy for $\ce C$, but $\ce{N2}$ is called nitrogen, $\ce{H2}$ is hydrogen and $\ce{Cl2}$ is chlorine, each having the same name as that of their constituent elements
- organic chemistry - Does Grignard reagent react with oxygen . . .
To add on to the answer by Waylander (edited by Nilay Ghosh): Waylander's reference does not actually propose reacting the Grignard reagent with oxygen in the presence of water
- Why is Density Functional Theory notoriously bad at describing oxygen . . .
The free energy change of total reaction: $\ce{H2O -> 1 2 O2 + H2}$ is fixed at the experimentally found value of 2 46 eV per water molecule This is done in order to avoid calculations of $\ce{O2}$, since this molecule has a complicated electronic structure, which is not described accurately with DFT
- Molecular term symbols for excited state oxygen
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
- Converting Disolved Oxygen from micromole L to millimole kg
$\begingroup$ one mmol is 1,000 µmol so that part is easy 1 L of water is about 1 kg of water, so that is not to difficult either (and if you want a slightly more accurate version use the known density of sea water but that will make little difference as it is typically ~1 02 kg L so won't affect the first decimal place in the result) so dividing your number by about 1,000 will give a quick
- Temperature of pure oxygen combustion - Chemistry Stack Exchange
$$\text{combustible stuff} \ce{+ O2 -> } \text{various oxides} + \text{heat}$$ 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 oxygen--but this is only because $\ce{N2O}$ generates oxygen itself
- How can carbon dioxide be converted into carbon and oxygen?
$\begingroup$ @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 Exchange
$\begingroup$ The 2 O represents two separate oxygen atoms, ( not connected to one another so free to move around and react independently ), the $\ce{O2}$ is molecular oxygen $\endgroup$ – porphyrin
