Jig Saw: Types of Reactions Form groups of 6 From the textbook (or your phone) study 1.Decomposition reactions 2.Synthesis reaction (combination reaction) 3.Single displacement reaction 4.Double displacement reaction 5.Combustion reaction 6.Acid base reactions

You will become an expert In one of the types and are allowed to take half an index card of notes You are given 30 minutes to prepare yourself ____________________________________ Then you will have 3-4 minutes to teach the peers in your group There will be an exit quiz

Decomposition reaction AB  A + B Hydrogen peroxide decomposes to yield water and oxygen gas. H 2 O 2  H 2 O + O 2

Combination Reaction or Synthesis Reaction A + B  AB Hydrogen gas and oxygen gas react to form water. H 2 + O 2  H 2 O

Combustion reaction C + O 2  CO 2 + H 2 O A compound such as carbon is burned in air to yield carbon dioxide and water Mg + O 2  MgO

Single Replacement Reaction A + BC  AC + B Copper reacts with silver nitrate to yield copper nitrate and silver Cu (s) + Ag NO 3  Cu (NO 3 ) 2 + Ag

Double Replacement Reaction AB + CD  AD + CB Sodium phosphate reacts with potassium hydroxide to make sodium hydroxide and potassium phosphate. Na 3 PO 4 + KOH  NaOH + K 3 PO 4

Acid Base Reaction a special case of double replacement The products are almost always a salt and water. Hydrochloric acid reacts with sodium hydroxide to yield sodium chloride and water. HCl + NaOH  NaCl + H 2 O
