It is joules per atom. Or, if you multiply by Avogadro's number then you will get joules per mole.
焦耳每个原子,或者,如果乘以,阿伏伽德罗常数你会得到焦耳数每摩尔。
If we want to talk about two hydrogen atoms, then we just need to double that, so that's going to be negative 2 6 2 4 kilojoules per mole that we're talking about in terms of a single hydrogen atom.
而要讨论两个氢原子,我们只需要把它乘以二,因此应该是负的,2624,千焦每摩尔,这就是单个的氢原子的情况。
Two moles of mag consume one mole of tickle, giving us one mole of Ti, and that's 515 moles of tickle consumed.
两摩尔的镁消耗一摩尔的四氯化钛,得到一摩尔钛,也就是说需要消耗掉515摩尔的四氯化钛。
Ordinary heat capacities are in Joule's per Kelvin mole, not kilojoules, right.
一般热容的单位是焦耳每摩,而不是千焦。
People can get hung up on sort of hunting these things down, and stamping them out, one at a time. And it's a little bit like playing Whack-a-Mole. Right?
我们可能会一次一个的去发现,这个bug并且消灭它,这有点像打鼹鼠对不对?,不停的有鼹鼠跳起来?
So, let's compare this to the energy of the h 2 molecule, and we find that that's negative 3,048 kilojoules per mole.
那么,让我们将它与氢分子的能量比一比,我们发现氢分子的能量是负的,3048,千焦每摩尔。
If I have one that's 400 kilojoules per mole and another that's 200 kilojoules per mole and I blend them, how do I get 500 kilojoules per mole?
如果你有一个每摩尔400千焦的分子,和一个没摩尔200千焦的分子,我把它们并子一起,我怎么得到每摩尔500千焦的键?
Cp, I forgot to put my little bar on top here because it's per mole Cp dT that's my dq here.
上面的Cv我忘记加上横线了,因为它也是摩尔热容。
Essentially we're not going to see this, it's 9 kilojoules per mole.
本质上我们不会看到它,它等于9千焦每摩尔。
Were going to make it for a mole of gas, T1 so it's R times T1, V and then we'll have dV over V.
假设是有一摩尔气体,那么就是R乘以,然后有dv除以。
And, one other thing that I failed to point out, if you take a look at the energies associated with the outermost electrons, in this case, lithium, you see it's 0.5 megajoules per mole, and then what's the 6.26?
还有另外一点我忘记提到的是,如果你观察离最外层,的电子的能量,在这种情况,对于锂,你可以得到,它是每摩尔0。5兆焦,那么6。26是什么呢?
Noticed that's not per mole, right.
我是说量热计是个很大的东西。
So, there's 1 mole of calcium carbonate.
这儿有1摩尔的碳酸钙产生。
Let's have one mole, n equals one.
因为是一摩尔,所以n等于一。
And, 435KJ/mol we can come up with a number of 435 kilojoules per mole HF Well, if we want to get HF, let's see what the FF bond is.
并且,我们想到一个数,如果我们想得到,我们看看FF键是什么。
If you go down to 1s, it's 20 MJ per mole.
如果再往下看1s层,是一摩尔20兆焦耳。
So for b 2, which is a single bond, that's 289 kilojoules per mole to break it, and it takes us more energy to break this double bond for carbon, which is 599 kilojoules per mole.
对于B2,它是单键,需要289千焦每摩尔来打破它,而对于碳双键,打破它要更多的能量,等于599千焦每摩尔。
