  • Whats the difference between 2O and O2 [duplicate]
    1 $\ce {2O}$ is basically two atoms of oxygen, unbonded and separate On the other hand, $\ce {O2}$ is oxygen molecule, which is more commonly called oxygen gas
  • 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
  • diH2O, dH2O, and DI H2O. What do they mean?
    What do $\ce {diH_2O, dH_2O}$, and $\ce {DI H_2O}$ mean? I'm not asking for a description of deionized water and distilled water I'm asking what the three abbreviations formulas mean In other wor
  • electrochemistry - Why is the water reduction of oxygen favored in . . .
    $\ce {O2 + 2e^- -> 2O^-}$ Or this? $\ce {O2 + 2e^- -> HOOH}$ 2) From the above we can deduce that water is the product; water is pretty stable in either acidic or basic medium - i e it won't react to a large extent with either hydronium or hydroxide ion Plus the oxygen in water has a -2 oxidation state So if we look at our skeleton half
  • How does a cyclization occur with a carboxylic acid and (CF3CO)2O?
    The product of the reaction below is unsaturated, bicyclic ketone, but I'm confused as to how (CF3CO)2O reacts with it to cause the cyclization There is no base involved so I don't know how the carbon delta to the carboxylic acid attacks it
  • Reaction of glucose acetal with acetic anhydride
    Starting from any cyclic form of glucose, there are two key ways to form the acetal in sequence (i) Taking glucopyranose as a starting point, here is a reaction scheme: Initially, you could argue that you can protonate either the free hydroxy group (left-hand path) or the cyclic oxygen (right-hand path) The two paths give you either of the two aldehydes in the third row The left-hand path
  • Finding the formula of an alcohol with a given molecular mass
    The general formula of alcohol is CnH2n+2O If you know the individual atomic masses of C, H and O, you can do some simple math to get your answer
  • What is the IUPAC name of N2O? - Chemistry Stack Exchange
    What is the IUPAC name of $\ce {N2O}$? I would usually say it's "dinitrogen monoxide", but its name is written as "dinitrogen oxide" in my textbook I don't understand how that
  • coordination compounds - Chemistry Stack Exchange
    The great problem is that the ability of a chemical substance to act in some way, is controlled by the activity of the substance and not by the concentration of it Oftein people consider the concnetration in a first approximation where the activity coefficent of everything is assumed to be one But for a good prediction or good undertsanding we need the activity coefficents for a species X
  • Why is 2H2O2 - gt; 2H2O + O2 a first order reaction?
    2 My book says that the reaction $\ce {2H_2O_2 -> 2H_2O + O_2}$ is a first order reaction and that it's rate equation is $\ce {k [H_2O_2] [I^ {-}]}$ However i don't see why that would be first order? Isn't the order of the reaction supposed to be the sum of powers of the concentration of the reactants?
