Chromium metal can be plated onto an object from an acidic solution of dichrmonate tions. What average current is required to plate 17.8 g of chronium metal in a time of 2.20 h? ( you will need to construct your own equation for the half-reaction)
Write the equation, determine the the atoms of chronoum metal, and then from the balaced equation the number of electrons to balance the equations.
amps= 1/chargeonelectron * total charge /time
