the question asks for the a balanced equation based on the reactants as seen below

C₁₂ H₂₂O₁₁ + O₂-----> ????

because it is a combustion equation it has to be

C₁₂ H₂₂O₁₁ + O₂-----> H₂O+ CO₂

then I start balancing and arrive at C₁₂ H₂₂O₁₁ + O₂-----> 11H₂O+ 12CO₂

this means I have 12 carbon and 22 hydrogen on both sides. but then oxygen happens I only have 13 on my reactants side and I have 35 on my product side.

I have no idea what to do next

*EDIT*

someone on the IRC told me I need to change the molar coefficient of the O₂.

which was all I needed to arrive at C₁₂ H₂₂O₁₁ + 12O₂-----> 11H₂O+ 12CO₂

so I guess this thread is going to be removed or closed or something....

It is a rare case where the question and answer are found in the same post, but there is no reason to remove or close it.

 

But it seems we're done here.
