  1. Types Of Chemical Reaction Reaction Types Mr H J Graham BSc PGCE

  2. Synthesis Reactions • In a synthesis reaction, two or more substances combine to form a new compound. This type of reaction is represented by the following equation. • A + B --------- AB • A and B represent the reacting elements or compounds AB the product Reaction Types Mr H J Graham BSc PGCE

  3. Synthesis Reaction 1 • Aluminium and bromine • Forms aluminium bromide • 2Al + 3Br2 >>>>>> 2AlBr3 • Watch the .MOV and then describe the reaction in your books Reaction Types Mr H J Graham BSc PGCE

  4. Synthesis Reaction 2 • Sodium reacting with chlorine • Forms sodium chloride (common salt) • 2Na + Cl2 >>>>>>>>> 2NaCl • Watch the .MOV file Reaction Types Mr H J Graham BSc PGCE

  5. Synthesis Reaction 3 • Zinc reacting with oxygen • Forms zinc oxide (sun block) • 2Zn + O2 >>>>>>>>> 2ZnO • Watch the .MOV file Reaction Types Mr H J Graham BSc PGCE

  6. Single Replacement Reaction In a single replacement reaction (displacement reaction) one element replaces a similar element These reactions can be represented by AB + C >>>>>> AC + B Reaction Types Mr H J Graham BSc PGCE

  7. Single Replacement Reaction 1 The famous Thermite reaction is highly exothermic. Aluminium is simply heated with rust 2Al + Fe2O3 >>>>>> Al2O3 + 2Fe + HEAT Watch the .MOV…..and then describe the reaction Reaction Types Mr H J Graham BSc PGCE

  8. Single Replacement Reaction 2 The reduction of copper oxide by carbon, produces copper 2CuO + C >>>>>>>>> Cu + CO2 Watch the .MOV…..and then describe the reaction Reaction Types Mr H J Graham BSc PGCE

  9. Single Replacement Reaction 3 How can you make silver crystals ? Watch the .MOV…..and then describe the reaction Reaction Types Mr H J Graham BSc PGCE

  10. Decomposition Reactions In a decomposition reaction, single compounds undergo reactions that produce two or more simpler substances AB >>>>>>>>>> A + B Reaction Types Mr H J Graham BSc PGCE

  11. Decomposition Reactions 1 What happens when Nitrogen Tri-iodide NI3 is tickled with a feather? Watch the .MOV…..and then describe the reaction Reaction Types Mr H J Graham BSc PGCE

  12. Decomposition Reactions 2 What happens during the electrolysis of Water Watch the .MOV…..and then describe the reaction Reaction Types Mr H J Graham BSc PGCE

  13. Fin Reaction Types Mr H J Graham BSc PGCE
