A student experimentally determines the gas law constant, R, by reacting a small piece of magnesium with hydrochloric acid and then collecting the hydrogen gas over water in a eudiometer. For each of the statements, identify how each error will affect the experimentally determined value for R. (a) The student does not clean the zinc metal with sand paper to remove the zinc oxide that formed on the surface of the metal. The experimentally determined value for R will be the gas constant reported in literature. higher than unaffected and should equal lower than (b) When the student does not tightly cap the eudiometer with the rubber stopper and during the reaction, some of the hydrogen gas escapes out of the eudiometer. The experimentally determined value for R will be literature. the gas constant reported in
