Guess its bit late but rusty nails turn a brownish orange colour, first stage of oxidation then turn black becuase they change to further oxidize Fe2 -> Fe3, however i think this is hypothetical question cause irl they don't turn black they basically deteriorate completely before that stage
Chemical equation for Stainless is found in ur textbook.
The reason is also in the textbook.
PS don't ask questions one night before something is due, do it in advance
