You know that the transition metals provide little help in defining trends, so why include them? Kids not confused enough? To be fair, however, a number of charts DO exclude them, so it's nothing original. Chemistry Virtual Textbook Acid-base chemistry can be extremely confusing, particularly when dealing with weak acids and bases. This set of lessons presents an updated view of the Brønsted-Lowry theory that makes it easy to understand answers to common questions: What's the fundamental difference between a strong acid and a weak acid? Can acid A neutralize base B? Why are some salts acidic and others alkaline? How do buffers work? Application of calorimetry - ChemWiki Bomb calorimeter is an isolated system and has constant volume. The bomb is a sealed container for the reaction occurring, and the heat of reaction will transfer to the water or oil in the inner container. The temperature changing of the water is usedto calculatethe heat of reaction. Bomb calorimeter is suitable for study of combustion reaction.
The Chemistry of Glow Sticks Click to enlarge Everyone’s familiar with glow sticks, but it’s likely that fewer are familiar with the chemistry behind their glow. You may have wondered what happens when you snap a glow stick to activate it; by doing this, you’re actually kicking off a chemical process that eventually leads to the production of the coloured light. But how does this process work, and why do you need to bend the glow stick to initiate it? Glow sticks actually contain two separate compartments, with two different chemical solutions. One solution, in the case of most glow sticks, contains a diphenyl oxalate compound, along with a dye whose identity varies depending on the desired colour.
