Question 3: Alumina is a widely used ceramic material with good thermal and electrical insulating properties. It is used in electronics, pumps, sensors, even as an abrasive or cutting material. It is widely found in nature, but it can also be synthesized by combustion: 4AI (6) +30,(9) 2A1,03 (6) A)- 3 marks: How many grams of alumina are formed when 13.2 g of aluminum powder react with 15.8 g of oxygen gas? Identify the limiting reagent and the mass of alumina formed. (8) - 1 mark: If the reaction takes place in a lab with a 67.2% reaction yield based on the limiting reagent, calculate the actual amount of alumina recovered in the reaction fi.e., how much product formed). 10-3 marks: How many grams of the excess reagent are consumed in the reaction? How many grams are remaining in the reaction vessel (i.e., how much unreacted material is left). Before proceeding to the mout ronn
