  1. I dont see here a production of glycerin. Only two oils, water and salt are mixed and heated. A yellow dull mixture was formed. There is no separation process to get rid of the fat acids and the glycerin. This needs caustic soda to crack the ester bonds. At the end the whole mixture was put on the skin, not good idea.
  2. I think in Amazon can find cheaper ones. https://www.google.com/search?client=firefox-b-m&sxsrf=ALeKk01FUiW1vzpqAJMdwBn7s5Ypmd4nGw%3A1604783802715&q=magnetic+stirrer+purchase&oq=magnetic+stirrer+purchase&aqs=heirloom-srp..0l2
  3. One of the best ones can found here, https://www.ika.com/en/Products-Lab-Eq/Magnetic-Stirrers-Hot-Plate-Lab-Mixer-Stirrer-Blender-csp-188/
  4. I love licorice. If it would not to far away I would buy them. But I guess you located in USA, it is to far and the shipping cost probably more then 12 bucks.
  5. Ammonia itself is a stable compound under normal circumstances. Needs higher energy to decompose.
  6. Not sure, if so then ammonia would be synthesist in this way and Not using high pressure devices.
  7. So far I understood a NO2/ N2 atmosphere was given. A hydrogen torch was burnt in it. Only 2 NO2 + 4 H2 => 4 H2O + N2 takes places. Yes some metals can react with nitrogen to built Nitrids, but hydrogen can not form ammonia under this circumstances.
  8. No, water will be obtained. Nitrogen will not touched.
  9. Its isopropanthiol (CH3)2CHSH The writing HSiPr could be misunderstanded as Si = Silicon, even the compound makes no sense.
  10. You have to bake it 2-3 h. I told NOx will be developed, so need good exhaust hood. Then amount depend of the size of the oven . As container a iron vessel would be ok.
  11. If you have Aluminiumnitrate, then you can bake it to 300- 400°C. It will decompose and release NOx and form the aluminium oxide.
  12. Why you need it, you create a lot of toxic waste. Better sell it und buy clean metal from a supplier. This is not for home. The normal way the distillation under low pressure, but also not for at home.
  13. Bisphenol A is bifunctional. For this reason it need ratio 1:2 , what means 1 mole bisphenol A to 2 mole epichlorohydrin.
  14. What happens if you mix both. In first case what do you get and in second case what do you get. Compare the two results.
  15. You wrote to much p- Electrons. Look up the total configuration of Krypton and Xenon.
  16. What is your question? The Synthesis is decribed in the Link.
  17. Add to coppersulfate solution or any other copper salt small amount of sodium hydroxide.
  18. Why you dont dissolved it in HCl and then evaporate and get the Iridiumchloride back.
  19. Nobody said to pour water into the acid. But this rule is so far only valid for sulfuric acid. Other acids don't develop so much heat.
  20. The acid has good soloubility in water. About 20 g/l at 20°C. But in oil it is almost not solouble. I dont know what is the problem. To dilute a solution from 98% to 2% is normal calculation method like cross rule and percentage calculation. To mix it with oils you need surfactants like soap.
  21. and the amount of CO2 is too high, So every body will die.
  22. H- is easy to get. Hydrogen react with sodium or other Smalltalk. 2 Na + H2 => 2 NaH. Sodiumhydrid.
  23. No, the full k shell is helium structure and very stable. So there can no additional electron to L, the same reason you can not make a He- .
