46. For each of the following unbalanced chemical equa- tions, suppose that exactly 5.00 g of each reactant is
taken. Determine which reactant is limiting, and cal-
culate what mass of each product is expected
(assuming that the limiting reactant is completely
consumed).
a. S(s) + H2SO (aq) → SO2(3) + H2O(1)
b. MnO3(s) + H SO.(1) ► Mn(SO)2(s) + H2O(1)
c. H S(3) + O2(8) SO2(g) + H2O(1)
d. AgNO3(aq) + Al(s) → Ag(s) + Al(NO3)2(aq)

the answer is (a) H 2 SO 4 is limiting, 4.90 g , 0.918 H 2 O : (b ) H 2 SO 4 is limiting, 6.30 g Mn(SO 4 ) 2 0.918 8 g H 2 O (c) O 2 is limiting, 6.67 g SO 2 , 1.88 g H 2 O : (d) AgNO 3 is limiting , 3.18 g Ag, 2.09 g Al(NO 3 )3
