Hess' Law is often stated in terms of standard enthalpies of formation.

赫斯定律通常用标准生成焓来表述。

Speaking of which, here is Hess' Law as a mathematical formula.

说到这里， 这里是赫斯定律作为一个数学公式。

We can just look them up in charts and plug them into Hess' Law.

我们可以在图表中查找它们并将它们代入赫斯定律。

Either in the back of most textbooks or on Google and plug them into Hess' Law.

在大多数教科书的后面或在谷歌上将它们插入赫斯定律。

First, we'll find the enthalpy change using Hess's Law and standard enthalpies of formation.

首先， 我们将使用赫斯定律和标准生成焓求出焓变。

So, I wonder how that compares to the amount we would predict using Hess's Law and the standard enthalpy of formation?

所以，我想知道这与我们使用赫斯定律和标准生成焓预测的量相比如何？
