No esterification, no phenylphaline, no magnesium, what do they let you do? Melt ice or maybe blow up baloons. ~Scott

Possibly yelling on a street corner cramming fliers down people throats. ~Scott

Something to be added to that list... 100 points-Claiming that they are a phychic channeling any great scientist. *shudder* ~Scott

Are you suggesting that it is perpetual motion, because thats just a world of wrong...

Hey this isn't a semiquatitive test for nitrates or anything but I have fish tanks too and as long as your regular on the water changes or in the case of a SW tank have a dsb then you shouldn't have to worry about testing for nitrates. ~Scott

The sun ~Scott

Well what I was talking about before in post #7 is only in a closed system. If the cola was left to freeze without being contained then the CO2 would escape and once the temperature normalised it would not be able to redissolve it. However if the system is kept closed then once to temperature pressure ect was returned to normal then the cola should be the same. As for taste well I have no idea but if I had to put money on it I'd bet it was just your mind playing tricks on you or it had still not returned to equilbrium. ~Scott

This movie was not popular in sydney but i thought it was not bad. One of the people being interviewed said that optimists being positive and whatnot was not very effective. I think it said something along the lines of "A smear of positive covering the surface of a large ball of negative" (This qoute is just from memory keep in mind I saw this movie a while ago). So that got me wondering what is the best way to percieve the world around us if not positively? Also I think that guy who was saying that he controlled the quantum world in such a way that it would show him and he would know it was his doing, ect, was a bit of a wank. The most interesting part of that movie was IMO the part about the freezing water and how our thoughts/emotions could effect it. Unfortunatly that guys website is not the greatest. ~Scott

Yeah ammonium nitrate is NH4NO3. That looks too expensive if it is american dollars and even if it isn't its still over. I think they sell it at garden stores as fertilizer that will be cheeper, YT will know good sources for this stuff he is the guru of chem scrounging ~Scott

What a mess indeed, I'm seriously of my game. ~Scott

What he means is that if the Ca was 2+ then it would not donate any electrons to the scandium and then you get no reaction. ~Scott

Batmobile kills But the only question is Does it come in black? ~Scott

I found this on http://www.davidwestclocks.com How is that perpetual motion? When the temperature changes there is input of energy. ~Scott

Other Batman sucked Sure this one does not repeat? The car is the bomb. ~Scott

What did you make it in? ~Scott

Hey sarah, seeing as your a regular why don't you start one thread in the chemistry forums that you post all your questions in? It will save some room and probably be more responsive then the homework help section. Just a thought. ~Scott

Thankyou Ewen Makes sense ~Scott

Get out, thats diprotic and seeing as you aren't given acidic constants you would have to assume that theoreticly the second dissociation could be 99%?? Or do you mean that the pH would be >2? ~Scott

Well there is no electrons paired or otherwise on the diagram around the carbon so i don't see where it would go. I understand where your coming from though it sems like it has four valence electrons and only three are being used so it should have a spare floating around. Aparently thats just not the way it sets itself up structually though, I don't know why it is like this but it is. ~Scott

Thats a bit hard to do without acidity constants eh? Do they give you those? Edit: Now that i think about it if you can't calculate I think it's experiment 3 because for that to be true it would have had to dissociate 100% and i don't think anything dissocitates perfectly. ~Scott

Tell you the truth this stuff is abit beyond me but I think you are right either one of the hydrogens on the first carbon should be removed or it should be carrying a negative charge. Formal charge ~Scott

No its got a neutral charge 3-0-3=0 ~Scott

Thats what i ment. ~Scott

Nope, valance electrons (4) minus lone pairs (0) - Half the total number of electronsin reactions (3) equals formal charge of 1. ~Scott

It won't react with zinc metal. ~Scott
