An electrochemical cell is based on these two half-reactions: ox: pb(s) ¡ pb2+(aq, 1.10 m) + 2 e- red: mno4 -(aq, 1.50 m) + 4 h+(aq, 2.0 m) + 3 e- ¡mno2(s) + 2 h2o(l) calculate the cell potential at 25 °c.

Suppose you got a low yield of benzoin from your benzoin condensation reaction and thus only have 0.300 g of benzoin to use as the starting material for this reaction. how much concentrated nitric acid should you add? (concentrated nitric acid is 15.8 m). write your answer in the form x. xx ml
