D oC 1.5 atm MnO2 • 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 Pressure Heat Temperature Catalysts (s) (l) (g) (aq)
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!)
Types of Chemical Reactions • Synthesis • A + X AX • Example • Water and calcium oxide • H2O + CaO Ca(OH)2 • Copy and paste URL to watch this reaction on YouTube http://www.youtube.com/watch?v=Y_FaU__XhPE
Types of Chemical Reactions • Synthesis • A + X AX • Decomposition • AX A + X
Types of Chemical Reactions • Decomposition • AX A + X • Example • Water • 2H2O 2H2 + O2 • YouTube Link: http://www.youtube.com/watch?v=EE58a5fN468
Types of Chemical Reactions • Synthesis • A + X AX • Decomposition • AX A + X • Single Replacement • A + BX AX + B • A+ BX BA + X
Types of Chemical Reactions • Single Replacement • A + BX AX + B • Y + BX BY + X • Example • Copper and silver nitrate • Cu + 2AgNO3 Cu(NO3)2 + 2Ag • YouTube Link: http://www.youtube.com/watch?v=dccDiAwztUQ
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
Types of Chemical Reactions • Double Replacement • AX + BY AY + BX • Example • Copper (II) chloride and sodium phosphate • 3CuCl2 + 2Na3PO4 Cu3(PO4)2 + 6NaCl • YouTube Link: http://www.youtube.com/watch?v=3thjr51qIN4 (Not the best video)
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 CO2 and H2O
Types of Chemical Reactions • Combustion • Carbon compounds CO2 +H2O • Example 1: • Isopropyl alcohol • 2 C3H7OH + 9 O2 6 CO2 + 8 H2O • YouTube link: http://www.youtube.com/watch?v=rA6l-TkGir0
