In the equilibrium system below, which of the following changes would cause the equilibrium position to shift to the right? co(g) + 3h2 (g) two arrows stacked on top of each other. the top arrow points to the right. the bottom arrow points to the left. ch4 (g) + h2o (g) delta h = -206 kj/mol (2 points) decreasing the concentration of carbon monoxide (co) increasing the volume of the reaction system decreasing the concentration of hydrogen gas (h2) lowering the temperature of the reaction

Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in the n=3 level to an orbital in the n=7 level.

1) these are barrel shaped microtubules in most animal cells, that organize the spindles during cell division

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?
