The basis for the carbon-14 dating method is that the basis for the carbon-14 dating method is that the amount of carbon-14 in all objects is the same the ratio of carbon-14 to carbon-12 in the atmosphere is a constant carbon-14 is very unstable and is readily lost from the atmosphere living tissue will not absorb carbon-14 but will absorb carbon-12 all of the above are correct. submit request answer

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?
