(a)
Answer to Problem 36A
H2SO4 is the limiting reactant
mass of SO2= 4.90 g SO2
mass of H2O = 0.919 g H2O
Explanation of Solution
The given mass of each reactant is 5.00 g
mass of S(s) = 5.00 g
mass of H2SO4 = 5.00 g
To determine the limiting reactant, first calculate the mass of H2SO4 needed for complete consumption of 5.00 g of S(s).
The given amount of H2SO4 is 5.00 g, therefore, H2SO4 is the limiting reactant, because it is completely consumed in the reaction.
Use the quantity of the limiting reactant, H2SO4, to calculate the mass of each product expected.

(b)
Answer to Problem 36A
H2SO4 is the limiting reactant
mass of Mn(SO4)2= 6.30 g Mn(SO4)2
mass of H2O = 0.919 g H2O
.
Explanation of Solution
The balanced equation is:
The given mass of each reactant is 5.00 g
mass of MnO2 = 5.00 g
mass of H2SO4 = 5.00 g
To determine the limiting reactant, we first calculate the mass of H2SO4 needed for complete consumption of 5.00 g of MnO2.
The given amount of H2SO4 is 5.00 g, therefore, H2SO4 is the limiting reactant, because it is completely consumed in the reaction.
Use the quantity of the limiting reactant, H2SO4, to calculate the mass of each product expected.
(c)
Interpretation:
The limiting reactant and mass of each product in the given reaction needs to be determined.
Concept Introduction:
The balanced equation is:
(c)
Answer to Problem 36A
O2 is the limiting reactant
mass of SO2= 6.67 g SO2
mass of H2O = 1.88 g H2O
Explanation of Solution
The balanced equation is:
The given mass of each reactant is 5.00 g
mass of H2S = 5.00 g
mass of O2 = 5.00 g
To determine the limiting reactant, we first calculate the mass of O2 needed for complete consumption of 5.00 g of H2S
The given amount of O2 is 5.00 g, therefore, O2 is the limiting reactant, because it is completely consumed in the reaction.
Use the quantity of the limiting reactant, O2, to calculate the mass of each product expected.
(d)
Interpretation:
The limiting reactant and mass of each product in the given reaction needs to be determined.
Concept Introduction:
The balanced equation is:
(d)
Answer to Problem 36A
limiting reactant is AgNO3.
mass of Ag= 3.18 g Ag
mass of Al(NO3)3 = 2.09 g Al(NO3)3
Explanation of Solution
The balanced equation is:
The given mass of each reactant is 5.00 g
mass of AgNO3 = 5.00 g
mass of Al = 5.00 g
To determine the limiting reactant, we first calculate the mass of Al(s) needed for complete consumption of 5.00 g of AgNO3
The given amount of Al is 5.00 g, therefore, Al is in excess. The limiting reactant is AgNO3, completely consumed in the reaction.
Use the quantity of the limiting reactant, AgNO3, to calculate the mass of each product expected.
