Tetrahedrite

It really doesn't matter what he was doing in Afghanistan, he should have had the presumption of innocence until proven guilty. If he was guilty of some offence against the USA, he should have been tried in a timely manner, not held in limbo for five years without being charged, or without the possibility of an even remotely fair trial.

Not quite sure how you are defining the term liberal. If you define everyone who is not a hardcore religious fanatic as liberal, then you probably have a point. Else, as others have noted, it really is a big leap to equate liberals with this nonsense.

No... the OP knew exactly what he was talking about, it is the rest of you who don't have a clue!!! As for the question, I have no doubt that Australia will win, that little hiccup with the Poms and the Kiwis will not be repeated when we have a full strength team. Furthermore, baseball doesn't even compare with cricket.

It is true that compounds such as wollastonite, CaSiO3, are common in the Earth's crust, but do you have any idea how much energy it would require not just to mine it, as bob000555 pointed out, but process it. The covalent and ionic bonds in Ca-bearing silicates is exceedingly strong, and I would suggest that you would probably produce around 5x as much CO2 in the energy required than you would extract. It is possible you could use gypsum, CaSO4, but once again mining it would probably get you back where you started (not to mention the world's gypsum supplies would probably be exhausted, a you also have a problem with disposing of the sulfuric acid you would produce. The world's scientists have considered this type of thing before, but have concluded it is unviable. The problem won't be solved by a high school science student with a poor grasp of chemistry.

Exactly. You have to get the Ca(OH)2 from somewhere.

I think you're missing the point, or your grasp of chemistry is rather weak, you can't create calcium out of thin air (easily:rolleyes:), and especially in the quantities required to remove even one person's contribution to global warming.

That's all well and good, you can use Ca2+ to remove carbonate from water and therefore CO2 from the air. But you have an enormous problem, where do you get the Ca2+ from? Nearly all the easily processable calcium used in industry is obtained from limestone. To obtain the Ca2+ from the limestone you need to release CO2, and thus you're back where you started.

......and a good thing too!!! Who in their right mind would want to live in the UK!?

It's only winter for some of you, for us in the south its summer!!!!

It really is funny how people can turn themselves inside out in an arguement. What you are advocating here is exactly what the trade unions do: putting pressure on companies/organisations/governments through strikes, bans, etc to get higher wages and better conditions. Collective action, as you describe, leads to a sort of minimum wage/set of standards for all employees in that particular sector/company. Trade unions in Australia also push for the national minimum wage to be raised.Trade unions are demonised (incorrectly IMO) for being socialistic and even communistic in many countries, and this seems to be the complete opposite of what you were advocating in previous posts?

It is absolutely sickening!! I'm sure that at least some people who frequent this site will try and defend this tactic. I take consolation in the fact that the tide of public opinion seems to be turning, and the number of "deniers" or "doubters" ( ) seem to be deminishing by the day.

It really is strange how right wing US politics is......In Australia, legislation like that would probably be supported by 90 percent of the population. It seems like good policy to me???

Don't forget Aluminium (Al), third most abundant element in the earth's crust!!!

Well colour me pink, you're right, I specialise in sucking at spelling. I just don't like the flavour of it. Or of aluminium. (Now I'm labouring the point a little).

No, I didn't...... Spelt is in the (Australian) english dictionary.

I thought the very same thing as I posted it, but decided I couldn't be bothered changing it to "wrongly" or some such thing. edit: you can probably understand why I'm having so much trouble writing my PhD dissertation, and why I'm procrastinating on SFN!!

Halfway through reading "the God Delusion" at the moment. But I have to say, it should be compulsory reading for everybody. How anyone could remain religious, or even agnostic after reading this I will never know??? What I like about Dawkin's is that he calls a spade a spade, and doesn't try to accommodate religion in any way, shape or form so as not to offend anyone.

I don't know whether you did it on purpose, but you have also spelt "labeled" wrong.

That's incredible:eek: If someone told me they had seen that, I would of said they were full of it!

Here is an example off the top of my head: How many moles are there in 100.0 mL of of pure hexane, C6H14? (density of hexane = 0.655g/cm3). If you can answer something like that I think you should be alright.

This was exactly my point above, I didn't think the reaction was " a fairly standard reaction equation" at all. Just a note though, the quantity for CuCl4(2-) and bisulfate that is formed is highly dependent on the concentration of the initial HCl(aq). Low concentrations will yield CuCl(-) and CuCl2(0) rather than the tetrachloride species.

If you don't mind Jdurg, could you explain it to me as well. Both CuSO4 and CuCl2 are exceedingly soluble, how is the H2SO4 extracted without getting HCl contamination????

You can be charged for riding a bicycle while under the influence in Australia.

Just finished the book Telling Lies for God by Professor Ian Plimer. An oldie but really good for anyone who wants to try and understand the tactics creationist crazies use to decieve their followers (and themselves). Highly recommended if you have not read. To tell you just how good it is, AnswersinGenesis.com have a 155 page rebuttal of his book!!! Ian Plimer is a Professor of Geology in Australia, one time president of the Sceptics Society and one time Humanist of the Year.

No problem. Thermodynamics is the fundamental driving force behind all chemistry so it really is a good thing to learn, even in a basic sense.
