Hey,

I got a question here that asks for the complete combustion of ehtene, C2H4.

I assume this means the reaction of ethene with oxygen? Thus, the equation would look something like this:

C2H4 + O2 --> C02 + H2O

Yes?

But the question also asks me to balance the equation, if the reaction is correct then I'm having a little bit of trouble finding the proper balance for the equation.

The course I am taking allows you to use fractions to balance reactions (ie 1/2). Is it possible to use both fractions and whole numbers to balance?

Jeez,

How silly of me... I overlooked the whole balacing thing...

Final answer I got is...

C2H4 + 3O2 --> 2CO2 + 2H2O
