  1. Do know Google? https://www.google.com/search?client=firefox-b-m&sca_esv=5d0811d5ae0715ef&sxsrf=ACQVn0-p-z-yyFyMDB0X402732ehGEwd5w%3A1713899584052&q=nanotechnology+books+&oq=nanotechnology+books+&aqs=heirloom-srp..0l5
  2. Because there are some more compounds in the battery like ammonium chloride, the practical voltage is 1,5 V https://www.azom.com/article.aspx?ArticleID=22363 The voltages can be found in electrical potential tables.
  3. Nernst law Potontials with positiv voltage minus Potential with more negative voltage gives potential between the two electrodes Here 1 V -(-0.26 V) = 1.26 V Zinc -0,763 V carbon-manganeseoxide +0,975 V 0,975V - (-0,763) = 1,738 V
  4. First what is the volume of your container Roughly you can calculate you have 3 part H2 and 8 part O2 means together 11 part equal to mol. Convert Fahrenheit to Kelvin 1058 F = 843,15 K p = 11 mol*8.314 J/molK* 843,15K/ V m^3
  5. Of course you will not find it to buy. You have to mix both compounds. It will react immediately. https://www.researchgate.net/figure/Synthesis-of-urea-glyoxal-resin_fig2_359692764
  6. That is a poor explanation. What is your question?
  7. https://www.quora.com/Is-urea-acidic-or-basic
  8. Beside your link I cannot find any other scientific link, where this is mentioned. Its more opposit, lime evaporate the nitrogen as ammonia, it is lost for the plants.
  9. Who says that
  10. The miscibility of liquids and the evaporation rate are different things. If you mix the three solvents they will dissolve directly. The compound of the highest vapor pressure will evaporate faster as the other ones.
  11. Ammonia is a gas at standard conditions, we cannot speak it has an pH, like water steam has no one. But liquid ammonia has also its autopotolysis like water it has. 2 NH3 => NH4+ + NH2- 2H2O => H3O+ + OH- So could have a pH scale based on ammonium theoretical.
  12. Its the opposit which I reduced an alkane to an alkyne. You reduce the alkyne to the Alkane.
  13. Why do you think it will not stop. If it works it will go through, even you have only two equivalent. Then some reactant will be left.
  14. If so why should it stop at acetophenon, this could react to 2 Phenyl-2-propanol. But it doesn't happen. If you use instead of the acid the ester then its possible.
  15. Carbonic acids cannot be treated with Grignard https://upload.wikimedia.org/wikipedia/commons/thumb/5/53/Grignard_with_carbonyl.png/450px-Grignard_with_carbonyl.png You can see they also treated CO2 to make carbonic acid. This would be not possible if carbonic acid would under go Grignard.
  16. Normaly its stable if you convert amines to the amid like acetamid. https://www.reddit.com/media?url=https%3A%2F%2Fi.redd.it%2F3jehma6dqs2a1.jpg&rdt=60302
  17. Ok Beside of neutrons, the other make it not radioactive, but it harm in other way as can read here. https://hps.org/publicinformation/ate/q13412.html
  18. If so then would be radiation no problem. Why the people afraid of nuclear power then. My expierence is: a cupboard in the lab got radiation where a container of K40 chloride was stored. It emittes gamma, beta - and beta+. What is your explanation for it. Why the people in Japan afraid to get the Tritium water from Fukoshima into the sea?
  19. I referred to the initial question, if material is exposed to alpha, beta or gamma rays . Nothing more, if it was unclear then I say sorry.
  20. Did I said something different.
  21. All material itself get radioactive, if exposed longer time to any of radiation. So there will be no steady material, metals and others.
  22. First this is not inorganic and second you asked it already in an other forum. We dont discuss to make pharmaceutical products.
  23. Ok this makes sense.
  24. My question is what is CrO3Cl-, I know CrO2Cl2 and CrO42- or Cr2O7 2-. Or is it a mixture of NaCl and CrO3?
  25. Do an Analyse of it. Dissolve in acid and use alizarin.
