    Three of those compounds can H-Bond. let's also try to rank them in terms of solubility in water.

    carboxylic acid is the most water suitable

    I got this wrong too, the first time I did it.

    It said... lol it's the Na2SO4 is the most water soluble out of all of them

    I knew it I was having a doubt between those 2

    yeah.. like I guess it makes sense because ionic compounds dissolve completely, in water.. but as for the order I think it would be the compound with the nitrogen<oxygen<carboxylic acid then< the ionic compound

    I agree wit you though the carboxylic acid would be the most out of the three b.c it has an additional LP to act as a hydrogen bond acceptor i think.

    Question is: which of the following gases is most likely to be ideal.

    You can eliminate right away two of the choices, the HF cuz of H bonding, and the alkene forgot what it was vanderwaals or something.

    For the first one, you can actually directly consider \(Na_2 SO_4\) to be the conjugate base of the very very strong acid \(H_2SO_4\), which according to wikipedia has -3 pka for the first hydrogen and 1.99 pka for the second hydrogen. Butanoic acid (which smells like puke, it's the stuff in rotten milk, and has a common name of butyric acid, it's gross) has a pka of about 4 since it's a caboxylic acid (you should or will eventually end up remembering this). The point of all this is Butanoic acid might lose its hydrogen because it's acidic, however you should think of the ionic compound as an acid that already lost its hydrogen because it's even more acidic. When it comes down to it, a "strong" acid is just really "weak" at holding onto Hydrogen atoms, which is kind of backwards haha. For the second one, like you said, just have to figure out which atom is smaller, He or Xe since the ideal gas approximation neglects particle-particle interactions. :P

    and yeah I never thought about it that way! at least wit the ionic compound(s). -3 pKa wow lol basically a ka >>>>>>1 lol

    the problem said something about Xe having more electrons so greater chance of interaction as opposed to Helium
