It is prepared industrially by the combustion of Hydrogen, in Chlorine, I don't think I would have the equipment at home. Making Chlorine Gas and Hydrogen isn't a problem they use an acid burner as far as I know.

There were a number of experiments I did in school using hydrochloric acid but I was not told how to make it. I found a video

It reads 5 molecules of water plus 1 molecule of Copper Sulfate gives 1 molecule of Sulfate Pentahydrate. Should include some reference to temperature/pressure for the reaction to occur. Which can be omitted. 1 Sodium Sulfate molecule plus 10 water molecules gives 1 molecule of Sodium Sulfate decahydrate http://www.sigmaaldrich.com/catalog/product/sial/403008?lang=en&region=IE These decas(10) and (5)pentas http://en.wiktionary.org/wiki/penta- are numbers in latin/Greek. There is also (8)Octa (4)Tetra (2)di (3)tri (6)exa/hexa (7)hepta

Cr's electron configuration, following the model would be: 1s2 2s2 2p6 3s2 3p6 4s23d4, but instead it is 1s2 2s2 2p6 3s2 3p6 4s13d5, because there is extra stability gained from the half-filled d orbital. Now you bond Chromium with oxygen. Chromium will be most stable 1s2 2s2 2p6 3s2 3p6 4s23d10 Therefore chromium wants 6 electrons from oxygen. The middle oxygen takes 1 all the time and the remaining three oxygens incompletely share the remaining 5 electrons. All the oxygens want 2 electrons.

Polar http://en.wikipedia.org/wiki/Chemical_polarity Ozone is similar Caused By the incomplete sharing of an electron pair.

Yes but a cell membrane is a selectively permeable(semi permeable membrane) not a permeable membrane.

As in a permeable membrane example.

permeable membrane? Can you provide an example please.

This drug does not exist on any reliable database that I know of.

Following a wiki error Passive transport is a movement of biochemicals and other atomic or molecular substances across a semi-permeable membrane.

Goldfish are fairly smart

There is another Alopurinol is a suggested beta-blocker on wikipedia http://en.wikipedia.org/wiki/Beta_blocker however the link goes nowhere http://en.wikipedia.org/wiki/Alpurinol . The closest it seems to know of is http://en.wikipedia.org/wiki/Allopurinol

Is it carithromycin or clarithomycin?

An anomaly. An alien race with superior technology. Perhaps instead of traveling time you move into an adjacent universe. That is exactly the same as ours only in the past.

Well that makes sense it probably meant contraindicating Triptans then abbreviated. Of course the abbreviation is wrong because contra means anti or opposed to so one would imagine a group of drugs which counteracted the effects of Triptans http://www.merriam-webster.com/dictionary/contra Other examples http://www.webmd.boots.com/pregnancy/guide/understanding-conception http://www.thefreedictionary.com/contraception

contraindications Said that too. Hang on got results minus an i contratriptans. Though not many

No that's all I know. I am looking for the definition. I already did a google search and a yahoo etc.

On the back of a box of medication just a word,

Looking for information about contratripitans.

PTFE is a self-lubricating material http://en.wikipedia.org/wiki/Lubricant Or effectively how much force does it take to pull a weight http://www.engineeringtoolbox.com/friction-coefficients-d_778.html

A finite amount of innovation.

wrong unfortunately Not here robots do most of the work. The country hasn't changed its ways with massive unemployment rates. Unemployed people don't get paid enough to live on. Even farmers might get hit with the driverless tractors http://www.fwi.co.uk/articles/23/01/2014/142566/does-the-future-lie-in-robots-or-driverless-tractors.htm You can't even work in computers because most people can't afford the servers.

Tic tac toe is always a draw.
