## Chemical equations

### Stoichiometric combustion of a hydrocarbon in oxygen

Generally, the chemical equation for stoichiometric combustion of a hydrocarbon in oxygen is:
$C_xH_y + zO_2 to xCO_2 + frac\left\{y\right\}\left\{2\right\}H_2O$
where z = x + ¼y.

For example, the stoichiometric burning of propane in oxygen is:
$C_3H_8 + 5O_2 to 3CO_2 + 4H_2O$

The simple word equation for the stoichiometric combustion of a hydrocarbon in oxygen is:
$textrm\left\{fuel\right\} + textrm\left\{oxygen\right\} to textrm\left\{water\right\} + textrm\left\{carbon dioxide\right\}$

### Stoichiometric combustion of a hydrocarbon in air

If the stoichiometric combustion takes place using air as the oxygen source, the nitrogen present in the air can be added to the equation (although it does not react) to show the composition of the resultant flue gas:
$C_xH_y + zO_2 + 3.71zN_2 to xCO_2 + frac\left\{y\right\}\left\{2\right\} H_2O + 3.71zN_2$
where z = x + ¼y.

For example, the stoichiometric combustion of propane in air is:
$C_3H_8 + 5O_2 + 18.55N_2 to 3CO_2 + 4H_2O + 18.55N_2$

The simple word equation for the stoichiometric combustion of a hydrocarbon in air is:
$textrm\left\{fuel\right\} + textrm\left\{oxygen\right\} + textrm\left\{nitrogen\right\} to textrm\left\{water\right\} + textrm\left\{carbon dioxide\right\} + textrm\left\{nitrogen\right\}$

### Trace combustion products

Various other substances begin to appear in significant amounts in combustion products when the flame temperature is above about . When excess air is used, nitrogen may oxidize to and, to a much lesser extent, to . forms by disproportionation of , and and form by disproportionation of .

For example, when …
