Question

What mass of ni2 is produced in solution by passing a current of 67.0 a for a period of 12.0 h , assuming the cell is 85.0 % efficient?

Answer 1

To calculate the mass of Ni2 produced in solution by passing a current of 67.0 A for a period of 12.0 hours, we need to know the stoichiometry of the reaction.

Step-by-step explanation:

To calculate the mass of Ni2 produced, we need to know the number of moles of electrons that pass through the cell. Given a current of 67.0 A and a time of 12.0 hours, we can convert the current to moles of electrons using Faraday's constant (96,485 C/mol). Multiplying the current by the time gives us the total charge passed through the cell. Dividing the charge by Faraday's constant gives us the number of moles of electrons.

To calculate the mass of Ni2 produced, we need to know the stoichiometry of the reaction. Since this information is not given, we cannot provide an accurate answer.

Answer 2

The mass of ni2 that is produced in solution by passing a current of 67.0 A for a period of 12.0 h and the cell is assumed as 85.0 % efficient is 766 Grams Ni. The answer to the question that was given above is 766 Grams Ni.
