When solid red phosphorus, P4, is burned in air, the phosphorus combines with oxygen gas, producing a choking cloud of tetraphosphorus decoxide (P4O10).
a. If 4.00 g of red phosphorus is reacted with 10.2 g of oxygen gas, how many moles of the excess reactant would be left over?
b. How many grams of P4O10 would be made?
c. Only 1.03 g of the product was made, what is the percent yield?
