Faraday's First Law of Electrolysis states that only, According to this law, the chemical deposition due to flow of current through an electrolyte is directly proportional to the quantity of electricity (coulombs) passed through it. i.e. mass of chemical deposition.
m quantity of
electricity
m = ect
Where
m = mass of metal deposited
c = current
t = time taken
Since m depends upon current used, electrolysis time & charge on the ion. But not on the molar mass
So the correct option is (D)
Answer is D, how come? All of the following affect the number of moles of metal...
1.) In Faraday’s electrolysis experiment, he used approximately 96,500 C of charge. A) How many moles of electrons is that? [This also explains where the unit of moles disappeared during the example in class.] B) We are going to use Faraday’s law of electrolysis to find the weight of a magnesium atom. [Magnesium has two valence electrons.] A current of 70.0 A flows through a solution of MgCl2 for 1.25 hours. Find the total charge and total number of electrons....
Part B and D
Please show all of the steps.
Learning Goal: To relate current, time, charge, and mass for electroplating calculations. Electroplating is a form of electrolysis in which a metal is deposited on the surface of another metal. To quantify electrolysis, use the following relationships. Electric current is measured in amperes (A), which expresses the amount of charge, in coulombs (C), that flows per second (s): 1 A 1 C/s Another unit of charge is the faraday (F),...
Be sure to answer all parts. How many moles are contained in each number of grams of table sugar (C12H2,011, molar mass 342.3 g/mol)? Enter your answer in scientific notation. a. 93.0 g b. 0.0690 g mol
Be sure to answer all parts. How many moles are contained in each number of grams of table sugar (C2H,201, molar mass 342.3 g/mol)? Enter your answer in scientific notation. a. 0.800 g b. 8.40 g mol
Be sure to answer all parts. Report your answer with the proper number of significant figures. Magnesium is used in lightweight alloys for airplane bodies and other structures. The metal is obtained from seawater in a process that includes precipitation, neutralization, evaporation, and electrolysis. How many kilograms of magnesium can be obtained from 7.00 km3 of seawater if the initial Mg2+concentration is 0.15% by mass? (d of seawater = 1.04 g/mL) I got 1.06 x 10^14 not right
How would the following errors affect the empirical formula of the compound for a hypothetical student performing s experiment? Note: Writing the answer will be incorrect is not sufficient for these questions. This student is not E) you nor is their data assumed to be the same as yours. student ran out of time and did not do the second heating. Explain thoroughly how this error will affect the water in the hydrate? Will the moles of water calculated be...
Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!
