Iron corrodes to produce rust, Fe2O3, but other corrosionproducts that can form are Fe(O)(OH), iron oxyhydroxide,and magnetite, Fe3O4. (a) What is the oxidation numberof Fe in iron oxyhydroxide, assuming oxygen’s oxidationnumber is -2? (b) The oxidation number for Fe in magnetitewas controversial for a long time. If we assume thatoxygen’s oxidation number is - 2, and Fe has a uniqueoxidation number, what is the oxidation number for Fein magnetite? (c) It turns out that there are two differentkinds of Fe in magnetite that have different oxidationnumbers. Suggest what these oxidation numbers are andwhat their relative stoichiometry must be, assuming oxygen’soxidation number is -2.

Impure nickel, refined by smelting sulfide ores in a blast furnace, can be convertedinto metal from 99.90% to 99.99% purity by the Mond process. The primaryreaction involved in the Mond process is:Ni(s) + 4CO(g) ⇌ Ni(CO)4(g)In the second step of the Mond process, the gaseous Ni(CO)4 is isolated andheated to 227°C. The purpose of this step is to deposit as much nickel as possibleas pure solid (the reverse of the preceding reaction). Calculate the equilibriumconstant for the preceding reaction at 227°C.
A steel sheet will have a thin layer of zinc put on one side to protect it from corrosion. Determination of the zinc film thickness per one centimeter square of steel sheet when a 2 A current is employed and the electrolytic deposition process is completed in exactly 30 minutes at 25 degrees Celsius. With a 1 M zinc solution, it's safe to presume that its concentration will remain stable throughout the process.
