could any one help me solve this question for right now
Nickel(II) sulphate solution was electrolysed using a carbon anode and an iron key as the cathode. A nickel coating was formed on the key, and oxygen was given off at the anode.
Write the cathode equation.
What mass of nickel would be deposited on the iron key if a current of 0.30 amps flowed for 15 minutes? (F = 96500 C mol-1; Ar Ni = 58.7)
Write the anode equation.
What volume of oxygen measured at room temperature and pressure would be produced at the same time? (Molar volume of a gas at rtp =24 dm3 mol-1)
