Types of reactions

  1. 1. 4 Types of chemical reactions-SYNTHESIS REACTION -TWO OR MORE SUBSTANCES COMBINE TO MAKE A MORE COMPLEX SUBSTANCE -example: - 2H2 + O2 → 2H2OHint: End with fewer types of molecules!
  2. 2. Decomposition Reaction:-one substance is broken down intotwo or more substances.-The opposite of a synthesisreaction! -example: 2NaClO3 → 2NaCl + 3O2 Hint! End with higher number of molecules
  3. 3. - Electrolysis (running electriccurrent through materials) isa method used to causedecomposition reactions toobtain pure substances.
  4. 4. Single replacement reaction-an uncombined element takes the place ofan element that is part of a compound.- example: Zn + 2HCl → H2 + ZnCl2
  5. 5. Zn + 2HCl → H2 + ZnCl2 Reactants Products Zn + H Cl
  6. 6. Double replacement reaction:-different atoms in two differentcompounds replace each other(two compounds react to form twonew compounds).-examples: 2K + P I b(NO3) 2 → 2K 3 + P 2 NO bI
  7. 7. Combustion Reactions• Combine a fuel with oxygen to produce water and carbon dioxide• 3 parts of this rxn are always the same!• Only the fuel will change• C2H6 + O2  H2O + CO2• CH4 + O2  H2O + CO2• C3H8 + O2  H2O + CO2
