2. Arrows means “yields” or “produces” or “forms Above the arrows put conditions necessary for the reaction States Small letter in parentheses showing its state solid liquid gas aqueous  oCoC 1.5 atm MnO 2Pressure Catalysts (s) (l)(l)(l)(l) (g) (aq) Heat Temperature

3. Types of Chemical Reactions - Overview Synthesis Synthesis – something is created Decomposition Decompose – something decomposes, breaks apart Single Replacement One part is replaced with something else Double Replacement Two parts are replaced with something else Combustion Something combusts (burning!)

4. Types of Chemical Reactions Synthesis A + X  AX Example Water and calcium oxide H 2 O + CaO  Ca(OH) 2 Copy and paste URL to watch this reaction on YouTube http://www.youtube.com/watch?v=Y_FaU__XhPE

5. Types of Chemical Reactions Synthesis A + X  AX Decomposition AX  A + X

6. Types of Chemical Reactions Decomposition AX  A + X Example Water 2H 2 O  2H 2 + O 2 YouTube Link: http://www.youtube.com/watch?v=EE58a5fN468

7. Types of Chemical Reactions Synthesis A + X  AX Decomposition AX  A + X Single Replacement A + BX  AX + B A+ BX  BA + X

8. Types of Chemical Reactions Single Replacement A + BX  AX + B Y + BX  BY + X Example Copper and silver nitrate Cu + 2AgNO 3  Cu(NO 3 ) 2 + 2Ag YouTube Link: http://www.youtube.com/watch?v=dccDiAwztUQ

9. Types of Chemical Reactions Synthesis A + X  AX Decomposition AX  A + X Single Replacement A + BX  AX + B Y + BX  BY + X Double Replacement AX + BY  AY + BX

10. Types of Chemical Reactions Double Replacement AX + BY  AY + BX Example Copper (II) chloride and sodium phosphate 3CuCl 2 + 2Na 3 PO 4  Cu 3 (PO 4 ) 2 + 6NaCl YouTube Link: http://www.youtube.com/watch?v=3thjr51qIN4http://www.youtube.com/watch?v=3thjr51qIN4 (Not the best video)

11. Types of Chemical Reactions Synthesis A + X  AX Decomposition AX  A + X Single Replacement A + BX  AX + B Y + BX  BY + X Double Replacement AX + BY  AY + BX Combustion Substance combined with oxygen, releasing energy Combustion of carbon compounds produce CO 2 and H 2 O

12. Types of Chemical Reactions Combustion Carbon compounds  CO 2 + H 2 O Example 1: Isopropyl alcohol 2 C 3 H 7 OH + 9 O 2  6 CO 2 + 8 H 2 O YouTube link: http://www.youtube.com/watch?v=rA6l-TkGir0
