When 10.00 g of lead and 1.56 grams of sulfur react, 11.56 g of lead sulfide is produced. Suppose 30.00 g of lead and 1.56 g of sulfur are allowed to react. Analysis of the reaction mixture would show
A. 31.56 g of lead sulfide.
B. 34.68 g of lead sulfide.
C. 11.56 g of lead sulfide and 20.00 g of lead.
D. no reaction.
