Tin reacts with hydrochloric acid to yield SnCl2 and H2(g). How many liters of hydrogen gas are produced at 27.0°C and a pressure of 710 torr if 1.40 g of tin is reacted with an excess of HCl? Please show the work.
The saturated calomel electrode (S.C.E.) is one commonly used reference electrode, with a potential of 0.242 V versus the S.H.E. Using a table of standard reductions, determine what the potential of each reduction below would be versus the S.C.E.
