What volumes of H₂ (9) and O₂ (g) at STP are produced from the electrolysis of water by a current of 2.50 A in 11.0 min? Volume of H₂(g) = mL Volume of O₂(g) mL Gold is produced electrochemically from an aqueous solution of Au(CN)2 containing an excess of CN". Gold metal and oxygen gas are produced at the electrodes. What amount (moles) of O2 will be produced during the production of 1.00 mol gold? Amount of O2 = mol Aluminum is produced commercially by the electrolysis of Al2O3 in the presence of a molten salt. If a plant has a continuous capacity of 0.600 million A, what mass of aluminum can be produced in 2.00 h? Mass= g
