Hydrogen cyanide, HCN, is prepared from ammonia, air, and natural gas (CH4) by the following process: Pt 2NH3 (g) + 30, (9) + 2CH, (g) → 2HCN(9) + 6H,O(g) Hydrogen cyanide is used to prepare sodium cyanide, which is used in part to obtain gold from gold-containing rock. If a reaction vessel contains 5.96 g NH3, 14.0 g O2, and 6.67 g CH4, what is the maximum mass in grams of hydrogen cyanide that could be made, assuming the reaction goes to completion as written? Mass = g HCN

b. (i) (ii) A green solid has the empirical formula FeBr3·5NH3 H₂O. Upon reaction with an excess of aqueous AgNO3 it is found that 1 mole of the solid precipitates 3 moles of AgBr. Heating the green solid leads to loss of 1 mole of H₂O to yield a blue solid with the same ratio of Fe:Br:NH3 as found in the green solid. The reaction of 1 mole of the blue solid with excess of aqueous AgNO3 produces 2 moles of AgBr. Draw and name the octahedral green and blue complexes. An octahedral complex having the formula [M(dien)(NH3)(OH₂)F] has a total of 15 isomers. In the sum formula "dien" represents the tridentate diethylenetriamine ligand, which can adopt meridional or facial coordination modes. Draw structures of 8 possible isomers, clearly showing any pairs of enantiomers. The tridentante ligand may be abbreviated as below for simplicity. H₂N : = ΝΗ NH :NH2 N diethylenetriamine (dien) N N
