A solid sample of a complex salt, with ideal composition
Ni(NH3)6(NO3)2, was
analyzed for nickel by dissolution in slightly acidic solution and
precipitation as the dimethylglyoximate, Ni(DMG)2.
A sintered glass crucible of mass 13.2379 g was used to filter
off the precipitate. The dried crucible and precipitate had a
combined mass of 13.3319 g.

1. Many important metals occur as sulfide, arsenide, and antimonide minerals, especially in the Sudbury mineral complex. The first step in processing these ores involves “roasting” the ore in air to produce the metal or metal oxide, along with nonmetal oxides that can be serious pollutants if not trapped. Suppose that you roast 2.00 kg of the mineral marcasite, FeS2. The balanced equation for the reaction is: 4 FeS2 + 11 02 → 2 Fe2O3 + 8 SO2 (a) How...
