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:(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the standard heat of formation of acetaldehyde, [tex]CH_{3}CHO[/tex] , given the following information:

[tex]CH_{3}CHO(g)+5/2O_{2}(g)\rightarrow2H_{2}0(l)+2CO_{2}(g)\triangle H=-1194kJ[/tex]

[tex]\triangle H{_f^\circ}~H_{2}O (g) [/tex] = -286 kJ/mol

[tex]\triangle H{_f^\circ}~CO_{2} (g)[/tex] = -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.
