Answer:

Al

Explanation:

The quantities in grams of each reactants are

94.51 g Al

1.873.10^2 g Fe_2SO_3

The grams of  Fe_2SO_3 are expressed in scientific notation

Since the power of ten is positive and is iqual <em>2</em> we must run the comma two spaces to the right

1,873.10^2= 187,3g Fe_2SO_3

Quantities of reactans expressed without scientific notation

94.51 g Al\\187,3 g Fe_2SO_3

The amount in grams of Al is less than the amount of Fe_2SO_3 therefore it will be finished first.

Answer:

sodium hexachloroplatinate(IV)- Na2[PtCl6]

dibromobis(ethylenediamine)cobalt(III) bromide- [Co(en)2Br2]Br

pentaamminechlorochromium(III) chloride-[Cr(NH3)5Cl]Cl2

Explanation:

The formulas of the various coordination compounds can be written from their names taking cognisance of the metal oxidation state as shown above. The oxidation state of the metal will determine the number of counter ions present in the coordination compound.

The number ligands are shown by subscripts attached to the ligand symbols. Remember that bidentate ligands such as ethylenediamine bonds to the central metal ion via two donors.
