Type of ReactionDefinition Equation Synthesis Decomposition Single Replacement Double Replacement Watch the movie and then complete the chart. A = Red B = Blue C = Green D = Yellow A + B AB AB A + B AB + C AC + B AB + CD AC + BD Two or more elements or compounds combine to make a more complex substance Compounds break down into simpler substances Occurs when one element replaces another one in a compound Occurs when different atoms in two different compounds trade places
Identifying Chemical Reactions ____ P + O 2 P 4 O 10 ____ Mg + O 2 MgO ____ HgO Hg + O 2 ____ Al 2 O 3 Al + O 2 ____ Cl 2 + NaBr NaCl + Br 2 ____ H 2 + N 2 NH 3 2. Use colored pencils to circle the common atoms or compounds in each equation to help you determine the type of reaction it illustrates. Use the code below to classify each reaction. S = Synthesis D = Decomposition SR = Single Replacement DR = Double Replacement
____ Na + Br 2 NaBr ____ CuCl 2 + H 2 S CuS + HCl ____ HgO + Cl 2 HgCl + O 2 ____ C + H 2 CH 4 ____ KClO 3 KCl + O 2 ____ S 8 + F 2 SF 6 ____ BaCl 2 + Na 2 SO 4 NaCl + BaSO 4
