OK, so what we have to do is get back underneath this reaction, and see what the molar quantities are.
我们应该做的是,再回到这个反应，看看摩尔量是多少。
-
However, the thing to remember is, when you look at heats of reaction under those conditions it's all well and good.
相反，需要记住，当你需要知道反应中放出的热量时,这些量是很有用的。
-
But, the reaction says I need twice as much mag as tickle if this reaction is going to go to completion.
但是这个反应告诉我们,镁的量应该是四氯化钛的两倍,如果要反应完全的话。
-
OK, so this, what I've sketched here would be a constant pressure calorimeter. There's a reaction.
好，我画的就是一个恒压量热计,其中进行一个反应。
-
So delta u of reaction is approximately equal T to negative Cv for the calorimeter times delta T.
所以反应的ΔU近似等于,负的量热计的Cv乘以Δ
-
Normally this is used for a reaction in the condensed phases and liquid usually.
通常它是用于凝聚态，液体相的反应,这是一个恒压量热计。

Anybody have an idea? What's the one function of state? I'm the system, the rest are the surrounding. What's the one function of state that's constant when I'm doing all my chemical reactions to move my arms around?
态函数又是什么呢？,我是一个系统，其余的是周围的环境,那么当我在做所有的化学反应,去四处移动我的手臂的时候,什么量是常数？
-
I've got reactants and calorimeter at T1.
我有T1下的反应物和量热计。
