How do I go about this without knowing any numbers?
Calculate ΔHorxn for the following equation:
SiO2(s) + 4HF(g) → SiF4(g) + 2H2O(g)

You can't do it without knowing the enthalpies of formation of all four substances. You'll just have to look them up!

Sat, in his answer, used this time period: "organic varieties" yet yet again period to search for, at the same time as describing a formation reaction, is this: "commonly used state" i'd also upload that a formation reaction is written for one mole of product. So, for instance, this: 2H2(g) + O2(g) ---> 2H2O(l) isn't a formation reaction (even notwithstanding all aspects are of their commonly used states), because it leads to 2 moles of product.
