Hydrogen gas (h2) and oxygen gas (o2) react to form liquid hydrogen peroxide (h2o2). which statement is true about the reaction?
the product that is formed has the same physical properties as the reactants.

the atoms of the reactants have combined to form a new substance.

the same atoms are present, so the chemical properties are the same.

the two gases have mixed together, but a new substance has not formed.

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?
