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

Let's say we are given:

[tex]CH_4 + 2O_2 \rightarrow CO_2 + 2H_2O[/tex]

We want to find [tex] \Delta_H [/tex] for the entire reaction.

Would I just use the formula:

[tex] \sum _i \Delta_H_i - \sum _j \Delta_H_j [/tex]? In other words just look up enthalpies in book and subtract enthalpy of reactants from enthalpy of products?

Thanks
