The left half-cell was loaded with 18.0 mL of Br, (1) (density = 3.12 g/mL). The aluminum electrode contains 13.8 g of Al. Which element, Br, or Al, is the limiting reagent? (That is, which reagent will be used up first?) Al Br, If the cell is somehow operated under conditions in which it produces a constant voltage of 1.50 V, how much electrical work will have been done when 0.390 mL of Br,(1) has been consumed? work = kJ If the potentiometer is replaced by a 1.35-k resistor and if the heat dissipated by the resistor is 1.75 × 10-4 J/s, at what rate (grams per second) is Al(s) dissolving? (In this question, the voltage is not 1.50 V.) rate: g/s The left half-cell was loaded with 18.0 mL of Br, (1) (density = 3.12 g/mL). The aluminum electrode contains 13.8 g of Al.
