Consider a Galvanic cell based on the following reaction: Ma (s) Mb (aq) Ma (aq) Mb (s) Two students are assigned to measure the standard cell potential. Yvonne claims that both solutions of ions have to be at exactly 1.00 M concentration, but Zelda is sure the measurement will be the same if the concentrations of the two solutions are equal, but not necessarily 1.00 M.

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.

Suppose a lab group reports a ppercent yield of sand of 105. is it really possible to collect more sand than was originally represented? what is the possible explanation for the extra product?
