The reaction of sodium peroxide and water produces sodium hydroxide and oxygen gas. the following balanced chemical equation represents the reaction.

2 na^2o^2(s) + 2 h2o(l) → 4 naoh(s) + o^2(g)

if 15.7 moles of sodium hydroxide are produced, how many moles of o2 will be made?

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?

An experimental procedure requires a 10 ml of acid to be dissolved
