The element phosphorus can be made by reacting carbon in the form of coke with calcium phosphate, Ca3(PO4)2, which is found in phosphate rock.
Ca3(PO4)2 + 5 C → 3 CaO + 5 CO
+ 2 P

completely with 66.34 Mg of
Ca3(PO4)2?
Mg
(b) What is the maximum mass of phosphorus produced from the
reaction of 66.34 Mg of Ca3(PO4)2
with an excess of carbon?
Mg
(c) What mass of calcium oxide, CaO, is formed with the mass of
phosphorus calculated in part (b)?
Mg
(d) If 10.90 Mg of phosphorus is formed in the reaction of 66.34 Mg
of Ca3(PO4)2 with an excess of
carbon, what is the percent yield?
