What is a faraday?
The main use of a Faraday is in the formula Q=nF. If this is rearranged, F=Q/n A Faraday is 96485 coulombs.
What is faraday constant?
•96485 coulomb/mol of electrons (for J) •23054 C/mol (for Cal) •23.054 C/mol (for kCal) •
What is the different between Coulomb and Faraday?
Coulomb is a unit of electric charge while Faraday is a unit of electric charge quantity present in one mole of electrons. One Coulomb is equal to one Faraday constant, which is approximately 96,485 coulombs.
What mathematical expression identifies the number of coulombs necessary to produce one mole of iron metal from an aqueous solution of iron III sulfate?
The mathematical expression is Q = nF, where Q is the total charge in coulombs, n is the number of moles of electrons transferred (in this case, 3 moles for iron III sulfate to iron metal), and F is the Faraday constant (96,485 C/mol). Therefore, the number of coulombs necessary would be Q = 3 * 96485 C/mol = 289,455 C.
How many grams of copper would be deposited during electrolysis of copper salt by a current of 7.50A for 600 hours?
To calculate the grams of copper deposited during electrolysis, you need to use Faraday's law. First, calculate the total charge passed in coulombs by multiplying the current (7.50A) by the time (600 hours). Then, use the molar mass of copper to convert coulombs to grams. The molar mass of copper is 63.55 g/mol.
In manufacture of potassium permanganate by electrolysis of k2mno4 what should be the equivalent weight of kmno4 how much kmno4 will be produced by 96478 coulombs or one farady?
The equivalent weight of K2MnO4 is 158 g/mol. To calculate the produced KmnO4, we first determine the number of faradays in 96478 coulombs (1 F = 96485 C). Then we use the stoichiometry: 1 mol of K2MnO4 produces 1 mol of KMnO4. So, 158 g of K2MnO4 will produce 158 g of KMnO4.
How much copper is deposited if a current of 0.2 amps is passed for 2 hours through a copper II sulphate solution?
To calculate the amount of copper deposited in coulombs, use the formula Q = It, where Q is the charge in coulombs, I is the current in amperes, and t is the time in seconds. Then, convert coulombs to grams of copper using the Faraday's constant (1 F = 96485 C/mol). Finally, calculate the mass of copper deposited.
How many megacoulombs of positive charge are in 1 mole of neutral molecular hydrogen gas?
Since 1 mole of neutral molecular hydrogen gas contains 2 moles of protons (H⁺) and 2 moles of electrons (e⁻), the total positive charge in 1 mole of neutral molecular hydrogen gas is equal to 2 moles of charge, or 2 faradays. This is equivalent to 2 x 96485 C = 192970 coulombs, or approximately 0.193 megacoulombs.
The electrolysis of BiO plus produces pure bismuth How long would it take to produce 10.0 g of Bi by the electrolysis of a BiO plus solution using a current of 25.0 amps?
To determine the time required to produce 10.0 g of Bi, you would first calculate the number of moles of Bi needed using the molar mass of Bi. Then, use Faraday's constant (96,485 C/mol) to find the total charge (in Coulombs) needed to produce that amount of Bi. Finally, use the formula Q = It to calculate the time required, where Q is the charge in Coulombs, I is the current in amps, and t is the time in seconds.
