Well the original post said that the poles were equal in everyway so the potenial difference through either of the positive poles East and South is equal to the potential diff to both negative poles Weat and North seeing as though North has the same potential to both positive poles east and south it will arc to the closer one east... ~Scott

I think table salt is pretty pure.. but seawater isn't, espechially if you live in a city there is heaps of polutants and substancial amounts of magnesium chloride in sea water too... ~Scott

Nice jdurg ive only got 10g of Gallium pretty pitiful in comparison i just wish mercury wasn't so toxic cuz gallium sticks to EVERYTHING!!!. ~Scott

Buckminsterfullerines, or sumthin' or other....

No problem all i did was google it...Also im pretty sure i heard somewhere (i know not very scientific) that bone was stronger then steel because it was more flexable. I would be inclined to disagree with that though.... ~Scott -
My teacher is a bit of a narc about these things so she would probably say empty it out and fill it again...but if you don't want to do that then I would use a pipette to suck a small amount out rather then let it evaporate as the solution would become more concentrated if you do that because the water will evaporate and the potassium iodate will not. ~Scott

The first two titration curves refer to strong acid/base titrations Here You can see the rapid PH change, you could use an indicator that changes at 7 8 9 6 5 4 you will get the same result even though the exact equivilance point is at 7. For other titration where the equivilance point dosn't have alot of values similar to it you should use a PH meter to determine the equivilance point. The HCl is not reacting with the methyl orange so adding excess HCl is not going to help with contamination by the methyl orange. ~Scott Edit: I would also suggest not using litmus it is one of the harder ones to see the colour change. There are other indicators that are easyer to see the colour change.

Sounds pretty good to me you may have some methyl orange contamination but that would be very minor. To answer your question there is a very large PH difference when titrating strong acids with strong bases. The curve would look like a slight increase followed by a very steep increase followed by slight increase. The reason you can use a variety of different indicators for strong acid/base titrations is that the equivalence point value is simlilar the value for a large range of PH values. Hope that made sense. ~Scott

Sorry but your post isn't very clear...re you talking about the O-H bonds? C-H? bonds or the bonds between the lone pair of electrons on an O of one molecule the H of another molecule? Maybe i could help you then... ~Scott

Here is a good website on nanotubes...It compares tensile strength and density of multiwalled and single walled nanotubes to steel ect but not skeletal calcium. Its also has the density values that you wanted I'll have to do a bit more looking for that bone stuff though. ~Scott -
I think that we as humans try to group or equate things to lines because we percieve the world in three spatial dimensions (lets leave time out of this one as we can clearly not agree on the direction its going...), that are all lines so its hard to describe the unfamiliar in anything but in terms of the familiar... ~Scott

The info in the link says photographic developer fluid and then someone else did it with argon bubbles in sulfuric acid...That would be pretty sweet if they could be used for nuclear fusion but seeing as though they can't reproduce the results maybe it was just a fluke... ~Scott
-
I agree with YT unless there was somekind of X shape insulator that would stop the arc from forming to the closer pole then they would not interesct but rather run parallel... ~Scott
-
Thanks for clearing that stuff up for me ~Scott

This is from Here Insects are so susceptable to it because they are tiny and their small systems are literally flooded by the boric acid quickly leading to toxic levels. In humans thios level takes alot more to reach. I'm not sure exactly what it does to the body to cause death though... ~Scott

Thanks for the replys, Ok so i get why we need Dark energy/matter to explain why the universe is the why it is but does any1 know what this stuff is? Can it interact with matter? ~Scott
-
Hi all, i'm not sure if this is the right forum for this but i think its more of an astrophysics question. Can somebody please give me the gist of dark matter/ dark energy? Is it like antimatter or what? Thanks in advance ~Scott

wow.....http://antwrp.gsfc.nasa.gov/apod/ap040915.html <= that got a five dot pause compared to my usual three... ~Scott

Scott, 17, Yes on one finger

I found this on another thread which i think was discussing the same stuff you are refering to. Parts by Weight ______________________________________ Potassium chlorate 18 Sulphur 6 black fine powdered aluminum (400 mesh) 6 Bran 2-2.5 However someone else suggests... white powder (ammonium nitrate). I knew it was because it was hard to burn. The other is a sensitizer which is a mix of aluminum powder, titanium sponge, and zirconium hydride (a powerful reducing agent). ~Scott

Yeah i thought someone would probly be around by now to correct me (if im wrong). Malachite is malachite formed in the wild or in a lab..... naturally formed malachite would have lots of impurities though... ~Scott

Some types of oxidation look really freaking cool.

Well I just poured my gallium from its plastic container into a glass vial. My first couple of attempts i suceeded in getting Gallium everywhere but the bottom of the vial. But i cleaned it all up except a small blob that fell on my floor and continues to evade me...Anyway whats the toxicity of gallium is pretty low huh like id have to ingest a serious amount to get sick right. ~Scott -

Surprising, i found cesium on ebay but in those ampoules that are heat sealed at both ends. So you can't stand them up, I wouldn't want a highly reactive metal in an ampoule that rolls around. But your right on the rubidium i couldn't find any...CsOH huh well we can only hope ~Scott -

Its weird how long Gallium stays liquid after its been taken down past its melting point mine satyed liquid for five days (then i put it into the freezer it lasted about 15 mins)... ~Scott -

You should definately get more osmium that metal looks realy nice. About the Gallium you should try melting it in the tube because gallium wets glass and looks really shiney if theres not much oxidation on it. ~Scott
