Answer:
8.82 gm of Pb
Explanation:
Question
calculate the Mass of lead that will be deposited from an aqueous solution of lead(2)salt by the same quantity of electricity that deposit 2.7 g of copper from an aqueous solution of copper (2)saltSince the oxidation# of the Pb and the Cu is the same, we know that the same amount of electricity that will deposit 1 mole of Cu will deposit 1 mole of Pb
2.7 gm of Cu were deposited
the atomic mass of Cu = 63.5
the number of moles of Cu deposited was 2.7/63.5 = 0.0425 moles
so 0.0425 moles of Pb will be deposited.
The atomic mas of Pb is 207.2
0.0425 mole of Pb weigh 0.0425 X 207.2 =
8.82 gm of Pb
Answer:
The answer to your question is: letter B
Explanation:
First, write the reactions and balance them
a. 2 CH3OH + 3 O2 ⇒ 2 CO2 + 4 H2O
ratio 3/2 = 1.5
b. 2 CH2 = CHCH3 + 9 O2 ⇒ 3 CO2 + 3 H2O
ratio 9/2 = 4.5
c. 2 CH ≡ CH + 5 O2 ⇒ 4 CO2 + 2 H2O
ratio 5/2 = 2.5
