What would be the effect (+, - or 0) on the calculated Rexp for each of the following? Please explain your reasoning in each case. 1. (a) The magnesium strip is not pure magnesium but instead has a coating of magnesium oxide on its surface. (b) At the end of the experiment the pressure is not equalized and the column inside the eudiometer tube is 5 cm higher than the level of the beaker. (See right) (c) Some Mg breaks free during the reaction and bubble to the top where it sticks to the side of the eudiometer tube.
