Using the equation:

Fe2O3(s) + 3CO(g) → 2Fe(s) + 3CO2(g)

(a) Show that this is a redox reaction. Which species is oxidized, and which is reduced?

(b) How many moles of Fe2O3 are required to produce 38.4 mol of Fe?

(c) How many grams of CO are required to produce 38.4 mol of Fe? Lead(II) nitrate and aluminum chloride react according to the following equation:

3Pb(NO3)2 + 2AlCl3 → 3PbCl2 + 2Al(NO3)3

In an experiment, 8.00 g of lead nitrate reacted with 2.67 g of aluminum chloride to give 5.55 g of lead chloride.

(a) Which reactant was the limiting reagent?

(b) What was the percent yield?
