Combustion- A hydrocarbon reacts with oxygen to form

carbon dioxide and water- CxHyOz + O2 CO2 + H2O

- 2 Reactants (hydrocarbon & O2), 2 Products (CO2, H2O)

- Ex: C2H5O (l) + O2 (g) CO2 (g) + H2O (l)

Combustion- Example: Write an equation for the combustion

of benzene. (C6H6)

Examples:2 C8H18 (l) + 25 O2 (g) 16 CO2 (g) + 18 H2O (l)

2HgO(s) 2Hg(l)+ O2(g)

CaI2 + Hg(NO3)2 HgI2 + Ca(NO3)2

2Mg + O2 2MgO

Fe(s) + Pb(NO3)2(aq) Pb(s) + Fe(NO3)2(aq)
