Module 13 lesson 1 notes

  1. 1. Reaction Types
  2. 2. Classifying Reactions• There are millions of substances and many different possible reactions• There are only a few general reaction types• Just like there are ways to identify the names of compounds, there are ways to identify types of chemical reactions and predict the products
  3. 3. Synthesis Reactions• Combine substances• Reaction of at least 2 reactants combine to form a product• A + B -- AB• Always join substances so the product is more complex than the reactant
  4. 4. Decomposition Reactions• Break substances apart• Reaction in which one compound breaks into at least 2 products• AB -- A + B• 2H2O -- 2H2 + O2
  5. 5. Single Displacement Reactions• Elements trade places• XA + B -- BA + X• Usually, a more reactive element takes the place of a less reactive element
  6. 6. Double-Displacement Reaction• Reaction in which a gas, solid precipitate, or a molecular compound is formed• Ions appear to be exchanged between compounds• AX + BY -- AY + BX
  7. 7. Combustion Reactions• Use oxygen as a reactant• Oxygen is a reactant in EVERY combustion reaction
  8. 8. Summary• Synthesis reactions make larger molecules• Decomposition breaks compounds apart• In combustion reactions, substances react with oxygen• Elements appear to trade places in single-displacement reactions
  9. 9. Summary cont...• In double-displacement reactions, ions appear to move between compounds, resulting in a solid that settles out in solution, a gas that bubbles out of a solution, and/or a molecular substance
  10. 10. Question 1• Classify each of the following reactions by type – A) S8 + 8O2 -- 8SO2 + heat – B) 6CO2 + 6H2O -- C6H12O6 + 6O2 – C) 2NaHCO3 -- Na2CO3 + H2O + CO2 – D) Zn + 2HCl -- ZnCl2 + H2
  11. 11. Question 2• Compare and contrast single- displacement and double-displacement reactions based on the number of reactants.• Use the terms compound, atom, element, and ion.
