Inorganic Chemistry

Hello, Does anyone know if there is any known living organism that consumes inorganic material as its only source of nutrition in today's world. I've heard it said that inorganic material had to be the only likely source of nutrition available to the first living cell, eons ago. Thanks, David James

What I am most interested in is what can oxidize NH3 to oxides of nitrogen at room temperature. Supposedly, hydrogen peroxide will react with ammonia in the presence of a catalyst, but there seems to be virtually no information about this in the literature. (whether the catalyst is iron salts or acetamide?) What exactly is the chemistry between H2O2 and NH4OH ? Does acetone serve as a necessary catalyst for the reaction? When the two are mixed, there is no observable reaction, and there are many references in the literature to mixes of the two chemicals, presumably without reaction. Under what conditions can ammonia be oxidized to NH4NO2 ? Excess H2O2 would presum…

To day, My aunt he's told me to show something, and he lift a breaker 100 mL with yellow solution and he heat it in few minute and he put iron nail 4" in it and wait for 3-5 Minute then he take iron nail up form yellow solution and clean it with water then he can break it ? I can confirm the iron nail is real My question : What solution be !? Aqua regia ? I think it is base on science please help me

Hi. What is alkane in "silver alkane" ? Does such material/compound exist ? Thanks

Please describe the distribution of electrons in an atom’s orbital and shells and how this distribution determines the chemical properties of atom. Thanks in advance

would i be able to dissolve calcium chloride in ammonia solution, in order to get a solution of ammonia and calcium chloride, or would the calcium chloride react with the ammonia solution and leave me with different products?

Does liquid neon retain its properties of lighting up when a charge goes through it the same way it does when it is a gas?

sir, anyone plz help me, its a chemical unknowen to me but know some properties, it is a white powder, when a pinch of this white powder kept on cotton cloth, add a drop of water, it reacts exothermically and emits flame it is light voilet colour, plz name some of white powders with these properties, plzzzzz

I've been looking for sulfuric acid. Where I live is quite hard to get it, so I think that I should give it a try to making it. I've seen something about electrolysing a solution of copper sulfate with inert anode and a copper/less reactive metal than copper cathode. Copper ions will be reduced to copper metal, and the water will be split into hydroxide ions, which would be oxidized to oxygen and water at the anode, and we are left with the sulfate and with the hydronium ions, which would combine and form h2so4. Is it really possible? In this case, can I use a 5v 40a power supply for this process? And platinum/iridium alloy as anode?Iridium is quite unreactive, right? WHa…

what woud be the best oxidizer to use in a solid fuel rocket using margerine and sugar as the fuel?

Hi, this article about production of foam glass, in our university we want to create new technic production from bottle waste. If somebody may help me with this question please write. As a foaming agent we use coal As a active agent we use boric acid It's the main question what do agents we may use instead of boric acid coal for extraction of carbon and oxygen? Also what kind of agents we can use for intensification of foaming process and for decrease of foaming process if the size of glass particle is 5-10 micron

Why is the electron gain enthalpy of fluorine less negative than that of chlorine ?

The total number of neutrons present in 54 ml(millilitre) water? i want full procedure

is there a way to make iodine with out using acids and peroxides? I was thinking mixing solutions of KCl/NaCl and KI/NaI would this work? not sure on the ratios but in theory should work...

Hi All, I'm reacting various types of limestone with 38% HCL to make Calcium Chloride Brine. Some older, hard grey limestones produce a very colorless CaCl2 solution. I'm currently using a very pourous, soft, oceanic limestone but I get a yellow CaCl2 product. How can I remove the yellow color? My method for making the CaCl2 is to react the acid with the limestone in a bucket to completion. I then raise the pH to 8.3 and filter with a buchner filter apparatus. Fe is 1 ppm, Mg is 75 ppm and Mn is 0.1 ppm. EMF is +375 at pH 8.3. However, the solution is yellow. I suspect its a residual organic from the limestone but how would I remove it. I …

Hello to everyone... I am a new at this forum... I am an Environmental Engineer, and I have a big (ok... not so big) question with a reaction I use at my experiments... I have two Reagents: Reagent A: 2% Na2CO3 in 0,1N NaOH Reagent B: 0.5% CuSO4*5H2O in 1% Potassium Antimony Tartrate (it has blue color because of the Cu) I mix 50ml of Reagent A with 1ml Reagent NOW!!! I have two cases: At the beginning I was adding to a 50ml volumetric flask filled with the A the 1ml of B the result was the creation (after something like 1hour) of a bluish emulsion (something I don't want to have) So... I tried once to add the 1ml of B to a beaker filled with t…

how would i make CS2 for use in the barking dog experiment (together with the NO/NO2 in my last thread) i did a quick google search and it wasn't too conclusive. would i be correct in thinking heating sulphur over crushed charcoal and a silica gel catalyst?

any one know how to make N2O with out using ammonium nitrate?

cn anybuddy suggest me how antimony pentafluoride can be hydrolyzed? one treament is with NaOH but i can't do it. pls suggest some other method?

Hi everyone, I'm currently designing an exercise for students for a website, which involves them sorting unfamiliar elements from an "alternate universe" into a periodic table of their own design. I'm not a chemistry specialist, and I've been a bit overambitious with my current design: orbitals hold 3 rather than 2 electrons! I seem to have hit a bit of a wall - in this universe, would the oxygen-like element be more likely to have 0 or 1 electrons in its last "2p-equivalent" orbital? Would it even be feasible for an oxygen-like element to exist? I mean, I think it would be sensible to have an element behaving like oxygen where it has 2 electrons in each of its "2…

Is anyone here familiar with boron chemistry and it's ability to form polymers and compounds similar to carbon? I have read where boron chemistry may exceed carbon chemistry in it's ability to form complex compounds. I have googled this but information about it is less than helpful in this direction.

After seeing the sticky thread in this part of the forum I had to speak up... First some safety: The experiment described uses corrosive chemicals and mixtures capable of burning without presence of atmosphere. It should be done outdoors in cotton clothing as fire protection, with chemically resistant gloves, and of course lab goggles. In case of fire, wait for initial reaction to subside, then use a class D extinguisher - do not attempt to put out fires with sand or water. A recent experiment of mine involved the production of the highly reactive element sodium from sodium hydroxide and another less reactive metal, in this case magnesium. The reaction is as follo…

In the chapter on solutions of Sienko & Plane's Chemistry the authors say that the amount of grams per liter of solution is not a reliable indicator of solubility, but the molarity --moles per liter of solution-- is, without explaining why. The following example is given. "At room temperature the solubility of saccharose [sugar] in water is 1311 g. per liter of solution, more than four times that of sodium chloride [table salt]. These figures are, however, misleading, and it is necessary to compare the molar solubilities if one wants to infer some consequence relating to the number of [dissolved] particles. The saturated solution of sodium chloride is 5.3 M, w…

Please can someone tell me where I can obtain some Caesium in Europe that is not from here http://www.elementsales.com/ I had a good place bookmarked but then lost it. Any help would be greatly appreciated. Thanks in advance.

does anyone have any Tellurium or Hafnium or boron to trade or sell? i have lots extra elements to trade also just let me know what you need and maybe we can work something out. i only need a gram or two of each and yes i know there are companies that sell these but I would have to buy a lot more then i need, plus by trading with someone its a win win since both of use would be able to expand our element collection. so i figured i would try here first instead of buying it from a company Merged post follows: Consecutive posts mergedno one?
