Determine the overall reaction and its standard cell potential (in v) at 25°c for the reaction involving the galvanic cell made from a half-cell consisting of a copper electrode in 1 m copper(i) nitrate solution and a half-cell consisting of an iron electrode in 1 m iron(iii) nitrate. (include states-of-matter under the given conditions in your answer. use the lowest possible whole number coefficients.) overall reaction
