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:
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?
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.
1). A sheet of aluminum foil with a mass of 25 g is taken from a room at 25° C and placed in a oven at 200.° C. How much heat does the aluminum absorb? The specific heat of aluminum is 0.90 J/g °C. 2). The value of AH° for the reaction below is -790 kJ. The enthalpy change accompanying the reaction of 0.95 g of S is 28 (s) + 302 (9) — 2503 (9)
