How to balance: C8H16 + O2 = CO2 + H20

Balance that chemical equation please, thank you :)

How to balance: C8H16 + O2 = CO2 + H20?
Balance that chemical equation please, thank you :)
--------------------------------------…
Remember, you must have the same atoms coming out as going in.

You have octene, C8H16, which produces 8CO2 and 8 H2O.

partial equation: C8H16 + ?O2 = 8CO2 + 8H20

Now look at the oxygen. you have 8 + 16 going out, so you must have (8+16)/2 oxygen molecules to start with.

final equation: C8H16 + 12O2 = 8CO2 + 8H20

check one final time:

8C, 24O, 16H...that's it.

Start with the C8H16 first. Each C8H16 creates 8 CO2 and 8 H2O.

_1_ C8H16 + ___ O2 ==> _8_ CO2 + _8_ H2O

Now, check the O's. The right side requires 16 for the CO2 and 8 for the H2O. That's a total of 24 which can be created from 12 O2 molecules. That balances the reaction.

1 C8H16 + 12 O2 ==> 8 CO2 + 8 H2O

C8H16 + 12O2 --> 8CO2 + 8H2O
