Question

what is the standard heat formation of F3O4. i know for F2O3 is -824.2. is this the same for F3O4????

Answer 1

I don't recognise the molecues. Are these hypothetical examples? The oxides of fluorine are F2O and F2O2.

Did you calculate the Hf for F2O3? the Hf for F3O4 will not be the same as that for F2O3.
