You could run the reaction, take solid iron and gaseous oxygen, form iron oxide, measure the heat of formation of it, and tabulate it.

你可以进行一个反应，用固态铁和氧气生成氧化铁，测量它生成的热，列成表格。

So I need to find out the heats of formation of the iron oxide and the water.

所以我需要找出氧化铁和,水的生成热，如果我这么做了。

And if I do that then I can find out the change in enthalpy of this reaction. It's just going to be the heat of formation of these three moles of water, minus the heat of formation of the iron oxide. OK.

我就能得到这个,反应的焓的变化,它就是三摩尔水,的生成热，减去氧化铁的,生成热，好。
