Ch. 7 Review Exercises
Complete the following problems starting on p. 179: #1-14, then 15 parts 'a-f' only, and finally 17abcd. Skip question #16. Make sure you have all 31 answers, worth 31 points. Write them up neatly IN YOUR OWN HANDWRITING. Keep the same numbering, please! Show all calculations or you will have points deducted.

ChemisTREE Silver Ornament lab
In this lab, we will plate Christmas ornaments with real silver, using the famous Tollen's reaction. Everyone will have a silver-plated ornament to take home.

Halogen Compounds lab
This is a classic chemistry lab comparing compounds made from chlorine, iodine, and bromine which we will make and observe.
This is a classic chemistry lab comparing compounds made from chlorine, iodine, and bromine which we will make and observe.
- The halogens are found in Group 7 (or 17) of the periodic table.
- Halogens have 7 valence electrons, so they would prefer to steal or borrow an additional electron from a metal like sodium or calcium, for example.
- The halogens are reactive. Chlorine acts just like oxygen, for example, attacking metals aggressively. You can "burn" pure iron in a container of chlorine gas.
- Fluorine is extremely reactive. It is called the Tiger of Chemistry. We will not be using fluorine in this lab exercise, as it tends to be dangerous.

Oil Spill Cleanup research assignment
Research and submit a 1-1/2 to 2 page report on the following – “The Deepwater Horizon explosion in 2010 spilled 5 million barrels of oil in the Gulf of Mexico. How could you use chemistry to clean up an oil spill? Describe what chemicals could be used, the mechanism by which they work, and any equipment which may be needed in the overall process. Include pictures and diagrams which help explain the process.”
