CP11 – Types of Reactions

Date

• Wednesday, September 21st

Recap – Balancing Reactions

• review homework
• examples with words! [LINK]

Practice with Words (write the full balanced equation)

• Magnesium metal is placed into hydrobromic acid solution,
  forming hydrogen gas and aqueous magnesium bromide.
• When heated, solid calcium chlorate decomposes into calcium
  chloride solid, releasing oxygen gas.
• Lithium metal reacts with oxygen gas to form solid lithium
  oxide.
• Solutions of barium bromate and sodium phosphate combine to
  form solid barium phosphate and aqueous sodium bromate.

New Material – Types of Reactions

• Double Displacement
• Single Displacement
• generic form – examples
• Predicting is NOT balancing
• Predict FIRST and then Balance

Practice – Write Full and Balanced Reaction for Each

• Na₂SO₄ + Pb(NO₃)₂ –>
• MgBr + AgNO₃ –>
• Aqueous solutions of copper(II) sulfate and potassium hydroxide are mixed together
• Aqueous solutions of aluminum chloride and lead(II) nitrate
  are mixed together

Homework

• safety assignment (lw01)
• prepare for the lab (lw02)
• NOTE: purpose, background, procedure, data in LNB
