Presentation Transcript

  1. Reaction Types

  2. Combustion Oxygen reacts and produces CO2 and H2O General Reaction: CxHx + O2 CO2 + H2O

  3. Synthesis, Combination Two or more simple compounds combine to form a more complicated one. A + B  AB

  4. Decomposition A complex molecule breaks down to make simpler ones (opposite of synthesis). AB  A + B

  5. Single Displacement One element trades places with another element in a compound. A + BC  AC + B

  6. Double Displacement The anions and cations of two different molecules switch places, forming two entirely different compounds. AB + CD  AD + CB

  7. Redox Reaction Fe is oxidized Cu is reduced OiLRiG Oxidation Is Losing electrons Reduction Is Gaining Electrons Fe + Cu2+  Fe2+ + Cu

  8. Acid-Base React to form “Salt” and Water Example: HBr + KOH  H2O + KBr

  9. Balancing Reactions Law of Conservation of Mass - Same number of atoms on each Use coefficients (numbers in front) to balance the equations. ___Al + ___FeCl2 → ___AlCl3 +___Fe 1 Al Al 1 1 Fe Fe 1 2 Cl Cl 3
