Over the past three classes many demos have been performed. Most of these are on youtube. Here are some links:
The following link is to a video that was done for an AP chemistry class two years ago or so the young videographer says. I do NOT recommend trying this because it is becoming increasingly illegal to explode anything in public places and, well, you would never do this indoors except under controlled laboratory conditions. Having said this – this video is being watched by young people – note the misspelled words (thier) and the young hands in the video – and it is important to understand this kind of chemistry that is easily available to the public – as failure to understand it has resulted in injuries. As we learned in class, Drano contains caustic lye and solutions of Drano can easily damage any exposed skin they contact.
Pay particular attention to the use of aluminum, a very active metal but only when the outer coating of aluminum oxide is removed.
We’ve been studying gases, especially gas stoichiometry. The exam is tomorrow and covers material in Chapters 1-5. I’ve noticed that folks are getting much better with the polyatomic ions. I will be holding a problem solving session tonight in Room 3162 at 7:40 pm. The class I am teaching tonight finishes at 7:30 pm.
