The student synthesise aluminum oxide according to this reaction: 4 Al(s) + 3 0,(9) + 2 A1,0,(s) Considering the mass of the limiting reactant she used, the student worked out that the theoretical yield of Al,0, is 3.208 g. She obtained an experimental yield of 2.329 g. What is the percentage yield for her synthesis? Answer:
Iron oxide reacts with aluminum in an exothermic reaction. Fe2O3(s) + 2Al(s) → 2Fe(s) + Al2O3(s) The reaction of 5.00g Fe2O3 with excess Al(s) evolves 26.6 kJ of energy in the form of heat. Calculate the enthalpy change per mole of Fe2O3 reacted.
Aluminum oxide (AIO) is produced according to the following equation. 4 Al(s) + 30,(9) → 2 A1,0,(s) If the reaction occurs with an 82.4% yield, what mass of aluminum should be reacted with excess oxygen to produce 45.0 grams of ALO?
