POST LABORATORY QUESTIONS 1. List two logical reasons why obtaining a 100% yield is unlikely. al b]_ 2. Write the three net ionic equations for the three main reactions in this experiment: Rxn 1 Rxn 2 Rxn 3 3. a] What is the most common oxidation state (charge) of aluminum? 4. Has aluminum lost or gained electrons to acquire this oxidation state? 5. Given the information below, determine the cost of making a 16.0 gram aluminum can from scratch. This is a unit cancellation/dimensional analysis problem. Al Al3+ 3 electrons One mole of electrons 96,500 Coulombs 1 kwh (kilowatt hour) 3.60 x 106 Coulombs Domestic electricity cost about 15.5 cents/kwh 16.0g Alx Imol Al 6. If the same can was made using recycled aluminum, what would be its cost? 153
