It should be Mg6Si8O22(OH)2. in Comparison to Na2FeI3FeIII2Si8O22(OH)2.

It gives more Foam.

Or tartric acid, malic acid,

It has to be. 2*1+3*2+2*3+8*4 = 46 to 22*(-2)+2*(-1) = -46

Any acid and any carbonate. All release CO2 Others will develop other gas mostly poison.

No discussions about pyro technic.

Yes. You misunderstood me. I agree what you said. By the way Im a safety officer in the company where I am working for.

What is the difference? Its a request and also a demand. Chemistry work and PSE has to be together.

That is of course a demand to wear the personal safety equipment, like goggles, gloves, labcoat, etc. ifworking with chemistry.

You can collect hydrogen and chlorine and burn it to HCl.

The assumption to get HCl is not right. On cathode you will get NaOH and H2, but on Anode you get Chlorine no clean HCl. The Chlorine react with water to hypochlorite and Chloride. Can buy as bleach. The method doesnt work. To get HCl treat NaCl with conc. Sulfuric acid. You get HCl gas what can be dissolved in water.

Sounds interesting. But as I told already do experiments. I am not sure it works especially hydroxylapatit has also poor soloubility. Think on the material teeth are made. In tooth paste flouride is added to harden it against caries.

One becomes wise by trying. "Aus Versuch wird man klug". Do some tests to see the efficency. I am not sure it will work, because of soloubility of Apatit is very poor. I would grind the material ( egg shell etc.) and put it in your device. Feed it it with sodium flouride solution and compare the contant before and after treatment.

I told you already its wrong in the other forum. The potentials are measured against hydrogen electrode. So is Zinc negativ - 0,76 V. In this table they look on one side for Oxidation and on other side for reduction. Li=> Li+ + e- is + 3,04 V Oxidation But in view of Reduction its opposit - 3,04 V This you can do for every element. But the standard reduction potential are measured against hydrogen. So you cannot mix it. The definition is delta E = Kathode (more positiv potential) - Anode ( more negative potential)

I think you have to test it. Also to Check if Dimethylcarbonate dont harm the poly styrene. I would start with 10 %.

You didn't Download the right document. On the first Page blue Button 473 PDF Here the right document synthesis of benzyl.pdf

Did you Download the PDF, there is ammonium nitrate used.

Cu2+ works as oxidiser. https://en.m.wikipedia.org/wiki/Benzil https://pubs.acs.org/doi/10.1021/ed065p553 Download the PDF from there

Neither nor, the volume is given of the container and is constant. The volume of the salt calculate before explosion.

Confusion with K equilibrium constant and k constant of rate law.

Without watching the movie, it is not possible to answer. In my opinion rule 2.7 has some nonsense. On one side people should not click any link and watch movies, on the other side it is told that videos should accompanied with enough text to set the tone of discussion. How to discuss a movie it its not allowed to watch. I think you have to check the rules for reasanable using. Or you are saying its not allowed to post any videos. Especial the topic of ways to dying.

The bandages were soaked with a highflammable substance, so the spark of the cigarette ash ignited it. Told at 1.30 min. He burnt alive. So don't smoke if you work with high inflammable substances, like fuel, ether, acetone, paint thinner, etc. Especially the cloth or gloves are contaminated with it.

Yes from the mole of the ammoniumnitrate you have to calculate according the chemical reaction of all gases. Additionall you have to add the air.

First convert the 577 g Ammonium nitrate into mol. You need molar mass for it. n = m/M From the chemical equation you see that 2 mol ammoniumnitrate refers to 2 mol nitrogen, 4 mol water and 1 mol oxygen. From the calculate mole above get them for the gases. look up specific gravity of NH4NO3 calculate the volume. From the given volume of the container subtract it. This volume is air. With the given pressure, temperatur and calculated volume use ideal gas law before explosion and get mol of air. Separate this to 79% nitrogen and 21% oxygen. Add all moles Mol fraction is Mf = nN2/(nN2+nO2+nH2O)

From the given equation calculate the mole of all gases, water is steam. Second from the given volume of the Container minus the volume of the solid salt calculate also the mole of nitrogen and oxygen of the air. Summarize of all moles and build the quote of nitrogen to the summery.
