Re: Videos of chemistry reactions on the molecular level

David, thank you for your feedback! It is always very helpful to find how the video looks from a professional point of view.    >it has a major misconception that ammonium chloride is a covalent molecule We for sure did not want to give such impression. Possibly this impression is the result of not formally right term "ammonium chloride molecule" for the complex of ammonia and hydrogen chloride as a single molecule, that is a covalent molecule (according to ab initio calculations). Combining into crystal these "molecules" surely become ionic ammonium chloride compound.  That is why it is very helpful to have feedback like your, it will help us to improve the video to make sure it is not understood in a wrong way.   >There is no mention of proton transfer from HCl to NH3  Proton transfer is there, but I agree that is not well seen on the picture and I agree we had to mention it in text. The visualization problem here is that proton transfer almost does not happen on the outer layer of the crystal. Moreover, the crystals we show in details are so small that this transfer is only seen in the very center. We did ab initio calculation of this process in GAMESS. Although the video more or less corresponds to what actually happens (it is not 100% ab initio quantum chemistry calculation of the process which would be too resource consuming, but combination of ab initio with molecular dynamic) it could easily mislead. We will think how to find a solution for this problem in the updated version of the video.   >and the crystal is described as an agglomeration of ammonium chloride molecules! Was it text or the picture that gave you such impression? As I wrote above, we did not mean that, but may be the outer layer of the crystal gave you such impression.   >At one point the narrator also talks of ammonia chloride. Do you mean the moment when he describes ammonia chloride molecules in gas or a crystal? I am not sure I could find the moment you mean.   Once again, thank you very much for your feedback! I really appreciate it. We tried to do our best in creating a video that is both visually beautiful and physically correct, but there are so many details that we could miss something, especially in the area how people will understand the video. Such comments like your help us to make the next version better.

Re: Videos of chemistry reactions on the molecular level

Hi Jane,    Thank you very much for your comment!    >using the term molecule for Ammonium Chloride ions is misleading   Do you mean the moment when HCl combine with NH3 to form a molecule of ammonium chloride or when NH4Cl molecules combine together to form a crystal?   I have found the following parts of the text where we spoke about ammonium chloride molecules: * This new molecule is called ammonium chloride. * Separate molecules of ammonia chloride combine together to form a crystal. * A small crystal nucleus grows bigger and bigger as new molecules of ammonia chloride join to it.   Do you mean one of them?   I agree that in the crystal there are no ammonium chloride molecules. However, I do not think we say so unless we our text is understood in a way we did not expect it to be understood, which is our fault if it is so.   Best regards, Vassili
