Ok, on this one I have no idea where to start. I could do all the homework ones, but have no clue even where to start on this. To me it seems backwards, but who knows. Here is the question:
Calculate the standard heat of formation of acetaldehyde, CH_{3}CHO , given the following information:
CH_{3}CHO(g)+5/2O_{2}(g)\rightarrow2H_{2}0(l)+2CO_{2}(g)\triangle H=-1194kJ
\triangle H{_f^\circ}~H_{2}O (g) = -286 kJ/mol
\triangle H{_f^\circ}~CO_{2} (g) = -394 kJ/mol
I'd show what I have so far, but honestly I have no idea what I am doing with this one.
Thanks for the help.
I'll probably have to end up redoing the LaTeX stuff because I can never seem to get it to work. It always says reload page in a moment in the preview.
