a) Determine the theoretical yield of the precipitate
b) formed when excessFe(NO3)3 are mixed with 4.00 mol of Na2CO3
When 10.0 grams of Fe(NO3)3 is added to 20.0 grams of Na2CO3, the limiting reactant is iron (III) nitrate. Verify that this is true and determine the number of moles of sodium carbonate that remains after the reaction has stopped.
