give five recommendation on how to recover more copper using electroplating ?
In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What mass of copper is deposited in 10.0 minutes? Avogadro's number is 6.022
Electroplating Postlab Questions 1. Suppose that you have the opportunity to be the first in the world to come up witha your data for the number of Coulombs of charge passed and the number of moles of value of Faraday's constant -never mind we al ready know it is 96485 C/mol e. Using copper actually lost from the copper electrode in your experiment, what would you predict for the value of Faradays constant? Show your work. What is the percent...

A student is given 1,2253 g of an unknown copper compound. Using magnesium to displace it, 0.5620 g of Cu metal is recovered. 3. What is the percentage of Cu in the sample? a. b. What is the formula weight of the compound? A student is given 1.403 g of pure CuO. To recover the Cu present in the compound, the dark powdery solid was dissolved in 15.0 mL of 6 M HCl, the solution diluted with 50.0 mL of...

How much more or less resistance does a cubic micrometer of copper have versus a cubic millimeter?
Using Atomic Absorption I wanted to measure how much copper was in a vitamin. The total vitamin when ground weighed 0.9687 grams. I dissolved 0.1049 grams in a 100 mL volumetric flask and measured how much copper was in that sample. It said there was 2.448 mg/L of copper in the sample. What was the total amount of copper in the vitamin?
26. How many grams of copper react to give 1.50 g Ag accord. ing to the equation in Exercise 25?
