Answer #1

From the given information we will write the following equations:

2NH3(aq) + Ni(NO3)2(aq) + 2H2O(l) → Ni(OH)2(s) + 2NH4+(aq)

                   Compound1                  compound 2(green)

Ni(OH)2(s) + 6NH3(aq) → Ni(NH3)6]2+(aq) + 2OH-(aq)

                                      Compound 3

Compound 1: Ni(NO3)2

Compound 2: Ni(OH)2

Compound 3: Ni(NH3)6]2+

Aluminum metal will reduce water, but the reaction is extremely slow under neutral conditions at room temperature.                 Al(s) + 3H2O(l) → Al(OH)3(s) + H2(g)                             very, very slow In the presence of aqueous base, however, Al will readily react to form the very soluble Al(OH)4–1(aq) complex anion which can be neutralized with H2SO4(aq) in two steps. The first produces the very insoluble Al(OH)3(s). If the Al(OH)3(s) slurry is then immediately boiled with additional H2SO4(aq) the insoluble hydroxide will react...
