2017年1月10日 · O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules. Our atmosphere is made of mostly O 2, which our bodies have evolved to breathe. We breathe in O 2 and cellular respiration requires it (C 6 H 12 O 6 +6O 2 →6CO 2 +6H 2 O). O is oxygen, while O 2 is dioxygen.

2020年6月2日 · Formation of truly long-living molecular O4 units also occurs but involves a considerably smaller fraction of O $_{2}$ molecules. So, it would seem that O $_{4}$ units, whether long lived 'molecules' or temporary short ranged order is the answer to the deviation from Curie's law in liquid oxygen.

2019年9月11日 · Not much electronegativity difference between O and F. The atomic size of Oxygen is not sufficient for it to hold 6 atoms. So which one is likely to be more appropriate, the d-orbital theory or the electronegativity and atomic size theory?

2016年1月6日 · The third C has a branch and an O (the chain continues after the braces close) which would have a single H attached, the third carbon has no H as the branch is attached via a double bond. (so far we have 3H) The first C in the branch has no H and attaches to another branch and another O with an H. The first C in the second branch has a single H.

2016年6月10日 · Hydrogen peroxide, on the other hand, as is evident from the structure in figure 2 below, contains not two $\ce{O^2-}$ units but a single $\ce{O2^2-}$ unit, composed of two oxygens bound to each other. This means that oxygen’s oxidation state is $\mathrm{-I}$ rather than $\mathrm{-II}$ and that hydrogen peroxide is readily reduced.

2014年2月6日 · Since $\ce{Mn+}$ has the highest charge density, I would assume that the $\ce{M-C}$ bond strength of the manganese compound is the strongest (vanadium being the weakest) and therefore, the $\ce{C-O}$ bond strength must follow the opposite order, as the strengthening of the metal carbonyl bond should weaken the carbon oxygen bond.

2018年2月21日 · This could be thought as an equivalent to the chelation effect in metal complexes. Lastly, one could also argue that in the case of o-hydroxybenzoinc acid, there is both the option of intermolecular and intramolecular $\ce{H}$-bonding compared to the para where there is only intermolecular $\ce{H}$-bonding.

2015年9月4日 · The main question is that manufactures also claim that it will provide DO, dissolved oxygen, to the solution. I find this hard to believe. Reason being, DO refers to dissolved $\ce{O2}$ (Dioxide) not Monoxide. When $\ce{H2O2}$ breaks down it breaks down to $\ce{H2O + O}$ (free radical), right? Can you please put some clarity into this?

The main problem was the fact that dioxygen readily oxidised simple Fe(II) complexes to Fe(III). Initially, Co(II) complexes (which only have one unpaired electron) were used: EPR studies showed that the unpaired electron was localised on oxygen, 4,5 and the length of the O–O bond resembled that of superoxide: 6

2016年7月20日 · In this case, $\ce{NO2}$ is called ambident ligand and is represented as nitrito-κ-N and nitrito-κ-O, replacing the old system of trivial names such as nitro and nitroso. Organic chemistry Alkyl nitrite forms two isomers: $\ce{RNO2}$ (called alkyl nitrite- N ) and $\ce{R-O-N=O}$ (called alkyl nitrite- O ).For preparation of these two isomers ...
