  1. Warm up 01-02-14 • Question: What type of reaction? MgO Mg + O • Answer: • Decomposition. • Goal: I will learn about endo and exothermic reactions.

  2. ELEMENT OF THE DAY • 47 – Silver – Ag • Silver is the most reflective metal, and the best electrical conductor. • The main problem with silver is that it tarnishes (reacts with oxygen). • Silver is much cheaper than gold, so it can be used in coins (and has been for about 3,000 years), but is still too expensive to commonly be used for electrical applications, so copper is usually used, which is only about 10% less conductive.

  3. Bellwork/ New & Good • Endo/Exo notes • Practice • Homework • Pg31-34 Agenda
