But the problem is that NaOH(aq) does not even exist! Thats not even a molecule, it doesn't represent anything, it does not represent NaOH in aqueous solution since it dissolves in ions there! The value of NaOH(aq) will always be zero since it never existed & will never exist. So the only...

The Kb for NaOH must be very high right? I found this online: The concentration of BOH what do they mean with that? The concentration of dissolved BOH or the concentration of solid BOH? Which phase does BOH represent?

sorry for the image: It should be

Hello, Ive been seeing it everywhere" NAOH is a strong base". But in order for it to be strong, it has to meet the requirements which are: -The Kb of the reaction 6qvtA.pngmust be high. This means that base strenght is not determined by the dissociation % of a substance. Now I ve seen a...

And what if they would ask "the rate of disappearance"? Do u have any idea what that might mean? Thanks!

Thanks, So u mean that it is not the rate of the reaction that is calculated in this example?

because the average rate always is calculated using this formula:

Hi, Im stuck: I found this example in which they calculate the rate of reaction: the title is "calculating the average reaction rate" Now how the hell is this average reaction rate if they didnt use stoichiometric coefficients!? (in this case it should be 2. Thanks in advance.

Hi, Could someone tell me if the following orbital diagram is correct for ozone? I added the bonds and lone pairs in color. Thanks in advance.

Hi, I have a question, because I am confused with the definition of surface tension. In my book it is defined as follows: "Surface tension is the energy required to increase the surface area of a liquid by a unit amount" What do they mean with increasing the surface area, how do you do...

Thank you my man :)

Hi, According to the molecular orbital diagram of the (C2)2+ ion you its a stable ion, because it has a bond order of 1 & that means its a stable substance. Now if you draw the lewis structure you could obtain the geometric arrangement of the electron pairs ( groups) around the central atom...

Thanks I really appreciate your help!

Hello, Is it true that according to molecular orbital theory valence electrons in molecules are not assigned to individual atoms? Does this mean that even lone pairs are not assigned to inidividual atoms in a molecule , but rather assigned to a specified area across the molecule? Thanks!

Hi, acutally I came to the conclusion that my previous statement might not be true afterall, because I found the following example in which no promotion occurs and still hybridization takes place: Does this mean promotion does not have to occur for hybridization?
