In a solution containing Tl (I) ions, for a constant current of .50 A for 10 minutes calculate the grams of deposit in the following situations: a) In the form of Tl2O3 (solid) on an anode? (b) as the element Tl (solid) on a cathode?
Atomic Weight (Tl)= 204
Atomic Weight (O)= 16
Isobutane is the fuel used in disposable lighters. The lighters' operation is dependent upon the butane's ability to vaporize and be ignited, and this depends somewhat upon the large pressure difference between the inside of the lighter
