# Qual è l'equazione chimica per la combustione del butano?

#### Risposta:

Butane + oxygen rarr carbon dioxide + water

#### Spiegazione:

C_4H_10(g) + 13/2O_2(g) rarr 4CO_2(g) + 5H_2O(g)

Is the equation above balanced? How do you know? How would you remove the 13/2 coefficient for dioxygen?

The reaction above represents complete combustion. Suppose I wanted to model a reaction where some of the hydrocarbon were combusted to CO; how would you represent this?
