In a simple molecule, that path is pretty clear: water-h2o-is hydrogen-oxygen-hydrogen balanced perfectly in a V-shape at a 104.4-degree Angle.

举个简单的例子，非常清楚的，水分子——H 2 O——是氢-氧-氢形成一个键角104.4度的V字形结构。

You need to know if it's an equilibrium, and you also need to know how many components you have in your system So, a glass of ice water with an ice cube in it, which is a heterogeneous system, has only one component, which is water, H2O.

要知道它是不是平衡的，你还需要知道,你的系统中有多少组分,一杯放了冰块的水，虽然它是个非均匀系统，但它只有一种组分，那就是水。

So it helps us predict, will we see this, for example, h 2, which we're going to be about to do, we'll see is stabilized because it has more bonding than anti-bonding.

这帮助我们预测，我们等会会看到，比如H2O，我们等会要讲到，我们会看到它更稳定是,因为成键比反键更多。
