How many grams of aluminum chloride can be produced from the amount of limiting reactant available? d. Calculate the mass of excess reactant that remains after the reaction is complete.

4moles of nitrogen gas are confined to a 6.0 l vessel at 177 °c and 12.0 atm. if the vessel is allowed to expand isothermally to 36.0 l, what would be the final pressure?

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?
