chemistry i have added a detailed list of pros and cons on the chemistry talk page why i think the picture with the reaction of water is more appropriate for the page than that of the flasks i hope to get some feedback from you and the other editor who reverted the first version of the new figure next time i add a new figure i will give a longer explanation up front thanks for the suggestion to discuss this on the discussion page i'm looking forward to a good exchange and am interested to hear was everyone has to say on this matter
