Synthesis A + B → AB
Two or more elements or compounds combine to form a single new compound
ExamplesH2 + O2 → H2O
CO + O2 → CO2
CaO + H2O → Ca(OH)2
Decomposition AB → A + B
Single compound breaks down into two or more simpler substances
Catalyst – substance that speeds up a reaction without altering it
Decomposition Examples HgO → Hg + O2
NaCl → Na + Cl2
Combustion Reactions Hydrocarbon- compound of C, H
and sometimes O Hydrocarbons combine with oxygen
to form carbon dioxide and water Examples
CH4 + O2 → CO2 + H2O
C2H8 + O2 → CO2 + H2O
C6H12O6 + O2 → CO2 + H2O
Determine What Type of Reaction Each Is, Complete, and Balance
H2 + O2 → Na + Cl2 → Al2O3 → C12H24 + O2 → CO → NH3 + HCl → CCl4 →
