1 Faraday of electricity = 96,485 coulombs and that amount of electricity will deposit 1 equivalent weight of a metal. The equivalent weight = molar mass/change in electrons (in this case delta n = 3). Coulombs = amperes x seconds

algebra uno help + check?
I think you are totally wrong. Take the last one. -x+2y=9 here are some equivalent equations: 2y-9=x x+9=2y 14y=63+7x Equivalent equations are equations that have the same solution.
