Calculate the binding energy per nucleon in MeV for the iron isotope with an atomic
number of 26 and a mass number of 56,
56Fe26 which has an atomic mass of 55.9349 amu.

The dichromate ion oxidizes iron (II) to iron (III) in acid solution. Balance the equation:
Cr2O
2- + H3O
+ + Fe
2+ → Cr3+ + Fe
3+ + H2O, by the half-reaction method

ΔHf/ KJ mol-1:
