1. Objectives: To predict products – using types of reactions Warm-up: Check your worksheets from last week and make corrections where needed. Types of reactions Single Replacement Predicting products Types of reactions: Balancing chemical equations

2. Review: Energy & Reactions Types Reaction TypeAnalogyEndo or Exo-thermic ΔH Synthesis Decomposition Single replacement Double replacement Combustion

3. Energy & activation energy https://ed.ted.com/lessons/activation-energy-kickstarting- chemical-reactions-vance-kite https://ed.ted.com/lessons/activation-energy-kickstarting- chemical-reactions-vance-kite

4. Single replacement reactions Element + compound → new compound + element magnesium + iron chloride  magnesium chloride + iron Lithium bromide + chlorine ↣ lithium chloride + bromine

5. What is special about single replacement reactions? Only more active elements can replace Use Activity Series charts Metals Halogens Use Reference Tables

6. magnesium + iron chloride  magnesium chloride + iron

7. Lithium bromide + chlorine ↣ lithium chloride + bromine

9. Practice: magnesium + iron nitrate  magnesium nitrate + _____________ Nickel + ______________  nickel ll sulfate + zinc zinc + ___________________  zinc II sulfate + copper zinc + iron chloride  ____________ + ____________
