Individual Round
This exam may test a broad set of general chemical concepts, requiring both numerical answers or written justification. The span of topics will closely follow that of the individual exams from WUCT 2017, but condensed into a single 1-hour exam.
Corrections (for "2018 Solutions")
- In part (c) of question 1, "that acetic solution" refers to the \(0.300M\) solution in part (b).
- In part (e) of question 5, given an appropriate explanation, both "endothermic" and "exothermic" are valid answers. However, since the question specifically states an answer must be based on the information in the question(see "Given this information"), only a complete answer that argues that the reaction is endothermic can receive full credit. A complete answer that argues that the reaction is exothermic can only receive up to 1 point of credit. This point of credit is given because, in the lab setting, the reaction is initially endothermic but becomes exothermic over time.
- In part (b) of question 3, given a complete explanation, an argument that \(Al\) and/or \(Mn\) protect \(Fe\) and slow corrosion is awarded 2 points. A complete argument that \(Cu\) speeds up corrosion and \(Al\) slows corrosion is awarded 3 points. An argument that the metals increase the voltage difference between those different metals is also awarded 3 points.
Corrections (unclear which this is for, check 2017 archive for the same wording)
- Question 1a.ii) The answer has has been changed. Molecular oxygen is the oxidizing agent and glucose is the reducing agent.

Team Round
Like the individual round, this exam may test a broad set of general chemical concepts. As all six students are allowed to work on this exam, though, the questions will require more in-depth interrogation of the ideas behind each problem.

Breaking Bonds
This will be a fast-paced, 60 minute round. Each team will receive a packet of 3 questions, of their chosen level of difficulty (easy, medium, hard). This question set will be completed at the team’s own pace and organization. Upon completion of the questions, the entire packet will be turned in and a new question set can be chosen, at the same or different difficulty. These questions will be drawn from a broad range of general chemistry topics.
