    To sleep or not to sleep

    No offense.. but that does sound very screwed up.. wonder how you'd feel if you're only a sex object.. (althought I don't doubt that you might like it) I personally think that it should be the opposite of what you have said, if you never find out you will have nothing to be disappointed...

    help with assignment question

    ummm.. the answer is yes, let's assume the saturated salt is mainly NaCl: Na+(aq) + Cl-(aq) -----> NaCl(s) (The final product is probably a Sodium Chloride nHydrate.. but I left it out for simplicity.. the formula is: NaCl.nH2O(s)) Clearly, when the such artefacts are left to dry, NaCl...

    Why do alkenes have lower MPs and BPs?

    hmm.. stargaze was right from the beginning I think.. generally the higher the molecular weight the higher the dispersion force between molecules because as the molecular weight increases, the number of electrons and size also increase. That will mean that the electron density is more dispersed...

    Sig Figs?

    Strictly speaking, the number of significant figures you use in your final answer should have at most the number of significant figures in the least accurate measurement. i.e. using the example you have given us: 25.0ml (3 sig. fig.) 0.1M HCl (1 sig. fig.) , 1.365g NaOH (4 sig. fig.) You...

    It's still smooth for the second time? :p I'm pretty sure they're not vanilla coke though.. I have something against vanilla coke - although I have never tried it.. anyways, so are yours :p aren't you going to post the other ones as well? Quis? Me? hehehe.. I love titration :p maybe we...

    O_______o.. it's still going :p lol.. Heisenberg only wasn't sure about quantum thing ;) he was pretty good at relationships (not).. apparently he took his ex-girlfriend on a week (or two..) of holiday to some place (I can't remember where..) when he came up with the equation :p not to mention...

    oh thankie to both of you xD hmm.. I forgot about that :confused: *sticks with bromothymo blue and phenol red* and.. *deleted* now you mention it, I seem to remember doing that in the titration competition during the standardising step.. hmm.. enough of talking to myself.. that was...

    q's on titrations - PLEASE help :D

    hmm.. nobody ever said about doing a weak acid - weak base titration.. I just was just commenting the acidity/basicity of the salt as a result of reacting a weak acid with a weak base.. and just out of curiosity.. I have never come across or read about using phenolphthalein as an indicator...

    q's on titrations - PLEASE help :D

    Some additions and amendments to the answers posted above: 1. I am assuming that the question you ask was: "why do we have to find out the concentration of the 0.1M NaOH instead of making a fresh new solution?".. in addition to the points xiao has mentioend, which add extra weight to the...

    shipwrecks n salvage help plz

    Hmmm... which text book do you use? I had conquering chemistry and the excel ones and they're good enough.. It shouldn't be that hard to find resources for this elective as they're mostly simple electrochemistry.. It's often hard for us to answer "everything", do you have particular questions...

    esters

    To make an ester you need an alcohol and an acid (you probably already know that :p) and in your case (ethyl ethanoate) the alcohol is CH3CH2OH and the acid is CH2COOH. CH3CH2OH + CH3COOH -----> CH3CH2O-COCH3 + H2O You would have used concentrated H2SO4 to absorb the water.. to simplify...

    Yup :) You are on the right track there casmira.. You may also want to know that HCl is a naturally occuring acid in our stomach.. I think it's ~2M. NH3 occurs naturally, too, mainly due to nitrogenous organic compounds :) (and obviously that's an example of a naturally occuring base) Basically...
