Warm-up Balance the following equations: Ba(OH)2 + HCl BaCl2 + H2O LiClO3 LiCl + O2 C6H14 + O2 H2O + CO2
A. Combustion • Hydrocarbon + oxygen carbon dioxide and water • CH4 + 2O2 CO2 + 2H2O • 2C8H18 + 25O2 16CO2 + 18H2O
Synthesis • the combination of 2 or more substances to form a compound • only one product A + B AB
Synthesis H2(g) + Cl2(g) 2 HCl(g)
Decomposition • a compound breaks down into 2 or more simpler substances • only one reactant AB A + B
Decomposition 2 H2O(l) 2 H2(g) + O2(g)
Single Replacement • one element replaces another in a compound • metal replaces metal (+) • nonmetal replaces nonmetal (-) A + BC B + AC
Single Replacement Cu(s) + 2AgNO3(aq) Cu(NO3)2(aq) + 2Ag(s)
Double Replacement • ions in two compounds “change partners” • cation of one compound combines with anion of the other AB + CD AD + CB
Double Replacement Pb(NO3)2(aq) + K2CrO4(aq) PbCrO4(s) + 2KNO3(aq)
