Synthesis Reactions • 2 H2 + O2 2 H2O • Two or more reactants combine to form one new product.
Synthesis Reactions • Example: • Sodium metal and Chlorine Gas combine to yield Sodium Chloride: 2 Na + Cl2 2 NaCl Click here for a synthesis reaction video.
Decomposition Reactions • 2 H2O2 2 H2O + O2 • One reactant breaks apart and becomes two or more products. Click here for a decomposition reaction demo.
Decomposition Reactions • Example: • Aluminum Oxide decomposes to yield Aluminum Metal and Oxygen Gas: 2 Al2O3 2 4 Al + O2 3
Combustion Reactions • CH4 + 2 O2 CO2 + 2 H2O • A hydrocarbon is usually burned with Oxygen gas to produce Carbon Dioxide & Water.
Combustion Reactions • Hint for balancing… 2 C4H10 + O2 CO2 + H2O 6.5 13 4 8 10 5 Double the reaction!!!
Single Displacement Rxns • Or Single Replacement • Li + NaCl LiCl + Na • The single element replaces an element in the compound to form a new compound. Click here for a single displacement demo.
Single Displacement Rxns • Metal replaces metal • Cu + 2 AgNO3 Cu(NO3)2 + 2 Ag • Or nonmetal replaces nonmetal • Example: • F2 + CaCl2 CaF2 + Cl2
Double Displacement Rxns • Or Double Replacement • NaCl + KBr NaBr + KCl • Two compounds are the reactants and the metals switch with one another.
Double Displacement Rxns • Watch out for Hydrogen, sometimes it acts as a metal! • NaOH + HCl NaCl + H2O
Double Displacement Rxns • When in lab, these reactions can produce precipitates, which are solid particles mixed in a liquid. [http://cwx.prenhall.com/petrucci/medialib/media_portfolio/text_images/FG19_P757-1a.JPG]
