### Exercises

Here you can find the Exercises which are an integral part of this course. The Exercises are related to different Lessons, and open at different times. **You can answer each question multiple times, but you can only submit the whole exercise once!**

Please take a careful look at this instruction file before starting working on the actual exercises.

**You can only return the exercise once for grading, so do not click the "Finish attempt"-button before you are absolutely ready!**Here you can find model solutions to the different exercises. The solutions will appear when the exercise deadline is met. Note that you may have had slightly different numerical values in the problem you solved. MyCourses picks different starting values for different students. You can calculate the answer to your specific question with the help of these models.

**Every multiple choice problem has a -50% penalty for wrong answers! Do not guess!** You can answer most of the calculation problems 5 times without penalty.

**Every chemical equation that you need to balance has a -25% penalty for wrong numbers! Do not try to guess the correct coefficients!**You can answer most of the calculation problems 5 times without penalty.

**Every multiple choice problem has a -50% penalty for wrong answers! Do not guess!**- During this exercise it is especially important to learn to draw correct Lewis-structures. Because MyCourses does not (yet) allow drawing to take place, the problems rely heavily on multiple choice questions.
**Every multiple choice problem has a -50% penalty for wrong answers! Do not guess, but draw the structures yourself and deduce the correct answers.** You can answer most of the calculation problems 5 times without penalty.
