Answer:

Butane + oxygen #rarr# carbon dioxide + water

Explanation:

#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?

Answer:

#color(red)(2)"C"_4"H"_10("g") + color(red)(13)"O"_2("g")##rarr##color(red)8"CO"_2("g") + color(red)(10)"H"_2"O(g)"#

Explanation:

The chemical formula of butane is #"C"_4"H"_10"#. The combustion of butane is a reaction between butane and oxygen gas that produces carbon dioxide gas and water.

#color(red)(2)"C"_4"H"_10("g") + color(red)(13)"O"_2("g")##rarr##color(red)8"CO"_2("g") + color(red)(10)"H"_2"O(g)"#
