We even balance equations on it.

我们甚至以对称形式保持等式。

Start by writing the balanced equation.

从写出平衡方程开始。

But there's a balancing equation, because children control the audible space in the house.

但是有一个平衡方程式，因为孩子们控制着房子里的听觉空间。

Each concentration is raised to the power of its coefficient in the balanced equation.

在平衡方程式中， 每个浓度都提高到其系数的幂。

So how do you do it? Not make a baby, balance an equation. I did biology last year.

你是怎么做到的？ 不生孩子，平衡方程式。 我去年学过生物。

We can use the coefficients from the balanced chemical equation to fill in the number of moles for each substance.

我们可以使用平衡化学方程式中的系数来填充每种物质的摩尔数。

First, convert your balanced equation into molar masses; in order to get from molecules to grams, you need to go through moles first.

首先，将平衡方程式转换为摩尔质量；为了从分子到克， 你需要先通过摩尔。

It must be a balanced equation you don't get it one way and not the other; you get to take credit when you also take accountability that's lesson two.

它必须是一个平衡的方程式， 你不能以一种方式得到它， 而不能以另一种方式得到它；当你也承担责任时， 你就会获得荣誉， 这是第二课。

And the reverse is it the same, except with C and D in place of A and B. Notice that these exponents are not however the coefficients of the balanced equation.

反之亦然，只是用 C 和 D 代替了 A 和 B。请注意，这些指数并不是平衡方程的系数。

Now this is important; we're using the coefficients as exponents here because we're multiplying all the products and all the reactants, not adding them like you would do in a balanced equation.

现在这很重要；我们在这里使用系数作为指数， 因为我们将所有乘积和所有反应物相乘， 而不是像在平衡方程式中那样将它们相加。

We also learned how to calculate molar mass and how to balance a chemical equation and finally, we talked about how to use molar ratios to calculate the amount of stuff that goes in and out of a reaction.

我们还学习了如何计算摩尔质量以及如何平衡化学方程式， 最后，我们讨论了如何使用摩尔比来计算进出反应的物质的量。
