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
An iron ore sample is a mixture of Fe2O3 and several impurities. A 752. g sample of the impure iron ore is heated with excess carbon. Only the Fe2O3 present in the ore reacts with the carbon producing 341. g of carbon monoxide by the following rea..
