Chemical Reactions
Unit 8 Ah, chemical reactions: the really fun part of chemistry. Mixing things together and standing back to watch what happens. After all, we now know plenty about chemical bonds (our previous unit)…it’s time to break some. We’ll be doing lots of that in this unit. We have three labs with plenty of opportunity to mix stuff, and identify strange substances. Our goals are to: 1. Figure out if a chemical reaction is occurring 2. Determine what type of reaction is occurring 3. Find out exactly what is going on by writing a balanced chemical equation 4. Become skilled at performing reactions by using appropriate solvents 5. Apply our knowledge to working with some acids and bases 6. Use all of this knowledge to identify mysterious unknown substances 7. Think about how we can perform chemical reactions using exactly the right amounts of reactantsthis will be the subject of our next unit: Stoichiometry. Tentative Schedule
