Thanks so much!

Chemistry
That helps. But I still don't understand why we subtract the reactants from the products in one case and when using bonds we subtract the products from the reactants.

Chemistry
Why do we have these two equations: ΔH° = ΣD (bond broken) – ΣD (bond formed) and ΔH = Σ ΔHf products - Σ ΔHf reactant I don't understand when we use which one and why? Please help. Thanks.
