The complete combustion of acetic acid, CH3COOH (l), to form H2O (l) and CO2 (g) at constant pressure releases 871.7 kJ of heat per mole of CH3COOH

the question asks for a balanced thermochemical equation for the reaction...

i set up the equation as:

CH3COOH (l) -> H2O(l) + CO2 (g)

i have been trying to balance this for a while... maybe i have the wrong equation but im not sure, could someone please help?

Almost.
You forgot to add oxygen to the reactant (left) side. Then it will be the correct combustion equation. You're right about always getting water and CO2 as products.

So it should be
2 O2 + CH3COOH Rightwards Arrow 2 H2O + 2 CO2
