Answer:
Explanation:
Trick question. The cathode is where the reduction reaction takes place. The reduction reaction is the gain of electrons.
Pb+2 + 2e^- ===> Pb The eo for that is - 0.126.
The minus sign indicates that the Pb^2+ is not overjoyed at taking on those two electrons. If it had a say in the matter, it would rather be giving up electrons. In other words, it would rather be the oxidizing equation which would look like this
Pb ===> Pb+2 + 2e^- and the oxidizing potential would be eo = + 0.126
That's what moving right and moving left means. If the eo is - then the preferred reaction is the opposite one.
This is a real language problem and if Znk answers you can take his answer to the bank.

Answer: If the theoretical yield is 2.35g then the percent yield is 80.4%
Explanation:
Given: Actual yield = 1.89 g
Theoretical yield = 2.35 g
Formula used to calculate the percentage yield is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that if the theoretical yield is 2.35g then the percent yield is 80.4%
