Imagine that you are a geologist trying to determine the amount of iron in the samples of rocks in a mountain side. A typical reaction used to determine the amount of iron in a sample is to combine it in a reaction with permanganate ion, MnO4-, with Fe2+ in an acidic solution. The skeleton reaction is: MnO4-(aq) + Fe2+(aq) --> Mn2+(aq) + Fe3+(aq)• Write the half reactions for this reaction.• Write the balanced equation for this reaction.
The reaction is: 2Al + Fe(III)2 O3 = 2Fe + Al2O3 If 1 kilogram of iron (III) oxide is used, what is the minimum amount of aluminum power to use to insure that all metallic iron that can be made is made
