Synthesis and Decomposition Reactions

1. Chemical Reactions Predicting Products of Different T ypes of Reactions

2. Classifying Reactions Synthesis Reactions (combination) Decomposition Reactions Single-Replacement Reactions Double-Replacement Reactions Combustion Reactions Neutralization Reactions

3. Synthesis Reactions Also called combination reactions Two or more substances react to form a single new substance Only 1 product in the reaction A + B  AB

4. 2 elements react to produce a binary compound 2Na + Cl 2  2NaCl 2Mg + O 2  2MgO S + O 2  SO 2 Metal oxide + water  metal hydroxide CaO + H 2 O  Ca(OH) 2 Nonmetal oxide + water  oxyacid SO 3 + H 2 O  H 2 SO 4

5. 1 . Ca + F 2  2. N 2 O 5 + H 2 O  3. MgO + H 2 O  4. Al + O 2  5 . SO 3 + H 2 O  6. K + O 2  7. Li + N 2  8. ZnO + H 2 O  9. P 2 O 5 + H 2 O  10 . K 2 O + H 2 O 

6. Decomposition Reactions A single compound breaks down into two or more simpler products AB  A + B Only 1 reactant

7. Metal chlorates  metal chlorides + oxygen 2NaClO 3  2NaCl + 3O 2 Metal hydroxides  metal oxides + water Mg(OH) 2  MgO + H 2 O Metal carbonates  metal oxides + carbon dioxide CaCO 3  CaO + CO 2 Oxyacids  nonmetalic oxides + water H 2 SO 3  SO 2 + H 2 O Binary compounds  individual elements 2NaCl  2Na + Cl 2

8. 1. CaCO 3  2 . AlCl 3  3. H 2 CO 3  4. KClO 3  5 . KOH  6 . MgCO 3  7. Al(ClO 3 ) 3  8. Ag 2 O  9. Fe(OH) 2  10 . Al 2 (CO 3 ) 3 
