What is the best description of the motion of surface currents? Question 2 options:

In the northern hemisphere the currents look like they are curving to the right; in the southern hemisphere, they appear to curve to the left.

The currents tend to curve to the right at both the northern and and the southern hemisphere.

In the southern hemisphere the currents look like they are curving to the right; in the northern hemisphere, they appear to curve to the left.

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?
