Study the standard reduction potentials given below and answer the questions that follow. (The letters are not the actual symbols of the elements).
(a)The standard reduction potential for #Fe^(2+)(aq)# is -0.44 volts. Select the element which would best protect iron from rusting.
(b) Calculate the Eθ value for the cell represented as:
#M(s)ǀM^(2+)(aq)ǁP^(+)(aq)ǀP(s)#
