A college chemistry student is performing this reaction in a lab, where magnesium is burned and combines with oxygen from the air to produce magnesium oxide. The students burns 2.92 g of Mg, and there is excess oxygen from the air. They incorrectly u'culated that the mass of magnesium oxide produced was 2.42 g. Here is their work: 2.92 g 1 mol 2 mol 40.3 g 2.42 g 1 24.3 g 1 mol 1 mol 1) What did the student do wrong? There is an error in their work. Explain specifically what part is incorrect. 2) What recommendation(s) would you give to the student regarding showing their work? There is an improvement that can be made to help them avoid this mistake in the future. pts) 3) Instead of 2.42 g, what answer should the student have gotten?

Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum(IV) bromide solution with aluminium metal. To test this purification process, a student reacted 14.6 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg of platinum metal. From this data, calculate the percent error of this experiment. Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first. Do not show your work in the space provided. Record only your final answer with the correct number of significant digits and the proper units. Answer: Evaluate your calculated percent error, is this an acceptable percent error?
