its the same with those "orbit" chewing gums , they contain sorbit and xylol which dont evaporate but they are moving and therefore they need energy which they "steal" from the warmth of your mouth then it feels cold.

just a clue there would be "peroxo" in the name if there are any O-O bondings.

glue reacts with O-radicals

Uve got to calculate , products - edukts = energy that is needed to form this compound 02(gas) has no energy and Na(solid) too , if the energy of Na2O is negative then its exotherm.

Just figure out the charge , like this: K can only be in +1 so K3P there must the P be in -3 and so on. Other examples are Oxygen , in compounds its in the majority of cases -2 charged.Or the earth-alkali metals ar always +2...

Agree , it occures when uve got ammonia and hcl standing next to each other.

Not actually,maybe i didnt make myself clear , but im looking for any kind of experiments or synthesis where you use electricity as an catalyst except as an provider for energy (sorry if im not clear with my questions) I mean like any other catalyst e.g platinum or whatever.

Yes , sure but are there any other applications for electricity as taking/giving electrons and the energy it's providing. Arent there any other reaction that can happen in order to speed up a reaction ??

Ive been wondering if there has been experiments with electricity as a catalyst , i especially think of the enegry its providing ? Maybe there are other catalytic properties except providing energy?

Copper(II)Chloride gives a really good green/blue flame if i remember well

sounds to me like yall got what you were after im happy for you!

Didn't know where to post this at , anyway i wish yall a merry christmas!

It depends on how much light the ions absorb , and if the rest light (the light the ions havent absorbed) is between 400nm and 800nm we can see a color. At least that what i think.

It always a sudden drop or rise if you use a strong base or acid , you see the 4th curve appears not to have a sudden drop or rise because there is a weak acid/base act. Addionally it has to do with the equivalence of acid and base , and when you add one more drop of strong base/acid it will result in a sudden rise/fall of your pH level. Hope i could help

great idea master

ever heard of zonal melting under inert gas , i bet it would work

next time think and get your information before you try to play the wisearce

thx for the polite answer.

Or you can just solve it in water ... You need an kathode made out of quecksilver , but you can read allt his in the existing thread.

Imagine you would be as fast as light , could you walk or wouldn't you be able to walk ?

there are none if you do it right. It always depends on how you do it and if u can estimate the risks :S

Thats true , it won't last long , just for a minute you feel abit numb , but its not like your totaly knocked out or something like that.

it's safe if you're well informed , there's a german page which clarifies poeple how to use it. Like not to much and they sell special apparates in order to not freeze the half of your face. But yes , still there's a danger , if you don't get enough oxygen , people can't estimate when you should stop.

What do you say about consuming N2O ? I do not often but still and it's much better than alcohol , a Chemistry Professor gave me this idea And it won't harm your body or something like that either Anyway , would you do it ?
