These questions require more thought and integrate several concepts.
Fluorine, F2, is made by the electrolysis of anhydrous HF.
Typical electrolysis cells operate at 4000 to 6000 A and 8 to 12 V. A large-scale plant can produce about 9.0 metric tons of F2 gas per day.
(a) What mass in grams of HF is consumed?
(b) Using the conversion factor of 3.60 × 106 J/kWh, how much energy in kilowatt-hours is consumed by a cell operating at 6.0 × 103 A at 12 V for 24 h?
We need at least 10 more requests to produce the solution.
