DisplayAds("Right1"); Hi everyone Here's the problem: The decomposition of ammonium hydrogen sulfide, (this rxn is reversible) is an endothermic process. A 6.1589 gm sample of solid is placed in an evacuated 4 litre vessel at exactly 24 degrees C. After equilibrium has been established, the total pressure inside 0.709 atm., some solid ammonium ...

This is a double post of an identical topic elsewhere. I am closing this thread. You may continue this discussion here: http://www.physicsforums.com/showthread.php?t=8429 9 Zz.

Look at the bottom of this page - http://irina.eas.gatech.edu/lectures/Lec13.html One needs the dissociation/dissolution constants for CO[sub]2[/url] in water under the P, T conditions.

DisplayAds("Right1"); I have a question: 2 glass containers have the same amount of a particular acid. In one container, drop a fully compressed spring retained in the compressed state by some means. In another container, drop a similar spring, in its free form. The acid in the containers start to dissolve the spring material. What happens to the stored energy in ...

If you want an explaination for what dexitroby( Sorry for misspelling) said I started a thread about the stability of electron orbitals, in atoms, moloceuls, and solids. Towards the end Gukul( Sorry potential misspelling) explained why transition metals fill up differently. The thread is towards the bottom and titled 'Stability of a full valence shell' or something like that. Hopefully this will...

resonance is just shifting of your electrons from one carbon to another or u can say shifting of bonds

DisplayAds("Right1"); Enthalpyof Combustion of 1 molar volume of H2(g) divided by Enthalpyof Combustion of 1 molar volume of CH4(g) = Enthalpyof Combustion per mole of H2 divided by Enthalpy of Combustion per mole of CH4 why???

We explain this phenomena with band theory; conducting and valence bands are very close to each other, providing rapid crossings with relatively low energy. Insulators are very low conductors, since the gap is too high for any electron to be excited.

DisplayAds("Right1"); I wonder if ethyl ether can react with cold concentrated H2SO4. I think that it cannot react but I still not sure because my books don't say anything about temperature condition. What about heated concentrated H2SO4, can it react without water or alcohol just only conc. sulfuric acid. Thank you for your kindness to answer these question.

DisplayAds("Right1"); So far I have done 14 out of 15 questions on the LAST problem set of the semester. I am stuck on one question, and no matter what I try, it wont accept my answer (the problem set is electronic). Here is the problem: "A galvanic cell consists of a Pt cathode inmmersed in a solution containing Fe2+ at 2.15 M and Fe3+ at unknown ...

Thanks for the diagrams. In my previous post I was trying to say that the two configurations which you have clearly drawn in picture 1 are both trans (wrt third carbon as centre). Is this a correct way of stating it? Or have I misused the language because whenever there is a trans there must also be a cis (otherwise don't use cis, trans lanaguage)? In this case there is no cis so I shouldn't...

Thank you for your interest, I'll warn my friend about being careful and about some precautions.
