Answer:
The total pressure P = 1.642 atm
Explanation:
From the dalton's law
Total pressure of the mixture is
----- (1)
atm
atm
n = 0.24 mole
R = 
T = 41 °c = 314 K
= 0.634 atm
From equation (1)
P = 0.419 + 0.589 + 0.634
P = 1.642 atm
Thus the total pressure P = 1.642 atm
Answer:
Electrons flow from anode to cathode (this is always the case). For an electrolytic cell however, this flow is not spontaneous but must be driven by an external power source. In an electrolytic cell, the anode has the "+" sign.
1) The amount of PbS produced will be 16.27 grams
2: The amount of Fe produced will be 118.72 grams.
<h3>Stoichiometric problems</h3>
1) The equation is balanced. The mole ratio of lead (II) acetate to the PbS is 1:1.
Mole of 22.11 lead acetate = 22.11/ 325.29 = 0.06797 moles
Equivalent mole of PbS = 0.06797 moles
Mass of PbS = 0.06797 x 239.3 = 16.27 grams
2) from the equation, the mole ratio of Al to Fe is 1:1.
Mole of 57.2 g Al = 57.2/26.98 = 2.12 moles
Equivalent mole of Fe = 2.12 moles
Mass of Fe = 2.12 x 56 = 118.72 grams.
