1. Explain at least one of the student's mistakes in their solution.

For this week's discussion, we are going to focus on analyzing and solving thermochemistry problems. The following problem was given to a student to solve on an exam. The student's solution has several mistakes. Problem: What is the heat absorbed in Joules when 25.0 g of PbSO.(,) reacts with excess water? 2PbSO (5) + 2H,0() - PD(s) + PbO2(5) + 2H,SO () Given: Pbs) + PbO2(s) + 2SO310) - 2PbSO(5) AHrxn = -768 KJ AHrxn = -132 kJ Solution: Flip # 1: 2PbSoy - Pb + PbOz + 250, +768 KJ Keep # 2: SO3 + H20 - Hz Soy - 132 KJ 2 pbsoy + 2tho - Pb + Pboz + 2tzsy + 636k] 25.0gx 636KJ = 15, 900 J In your initial post address the following three points: 1. Explain at least one of the student's mistakes in their solution. 2. This problem is worth 10 points on the exam, how many points do you think this student should be awarded for this problem and why? 3. What suggestions would you give to this student for studying in the future
