Oxidation-reduction is often the most confusing and abstract part of chemistry for first-time chemistry students. is it really worth the trouble? think about the various chemical reactions that impact your life and society daily. now, which ones are oxidation-reduction reactions versus some other type of reaction? think about these reactions—redox or not—and take a reasoned position about the importance of redox reactions in our lives.

How many moles are equivalent to 55.5g of nano3

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
