So, if we hybridize just these three orbitals, what we're going to end up with is our s p 2 hybrid orbitals.
我们会看到现在有3个未配对的电子,可以成键。
Where, you know, you might have a single family that is using up 2 or 3 stories of the same apartment.
一个家庭也许会用上同一幢公寓的二三层楼。
And what we end up with for the energy then is 2.84 times 10 to the -19 joules.
我们算出的能量是,2,84乘以10的-19次方焦耳。
And I look up and see that 55 the electronegativity of carbon is 2.55 2 we already know, is 2.20.
我查了一下电负性,碳是2。,2。
I go up to the green line and go across and this tells me the best response for Firm 2.
根据这条绿线的对应法则,就可以对应出公司2的最佳对策
Then if you adjust for survivorship bias, you end up concluding that the deficit wasn't .3% but the deficit was actually 2%.
那么如果你算上生存偏差,你会发现,缺口不是0.3%,事实上是2%
And yet if a computer can only count up to 2 billion or maybe 4 billion, I mean, what do you then do?
如果一台计算机只能够支持20亿,或者40亿,那我们该怎么办?
And the second point is of radius 3 and angle 1, which is up about there.
半径为2然后角度为1的一个点,也就是差不多在这儿,我认为为了确保我做的是。
I think recently were up to 230 million.
最近更是上升至2亿3000万。
Sometimes there are completely new emphases and the story can come out to be a very, very different story. 1 and 2 Chronicles are a retelling and a reworking of much of the material from Genesis through 2 Kings, and it cleans up a lot of the embarrassing moments.
复述的故事会有全新的侧重点,可能和原来的故事之间,存在很大的差别,《历代志》上下就是,对从《创世记》到两部《列王纪》中大量材料的复述和,再加工,它清除了很多令人窘迫的故事。
When they started to calculate how much rice would be need to fill up all blocks, all the way to 2 to the power 63.
当他们开始计算,需要多少粒米填满所有方格时,从第二格到第63格。
Two-thirds of the average was 9 and some of you chose 9, so if you are here, stand up.
平均值的2/3是9,有人选了9,所以如果你选了9请起立
So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.
比如,在这下面我写的是氮分子2,而这个是氢分子,但我在上面把这些分子的形式改写了,大家可以看到,这是一个氢与氢之间的单键,含一个氮与氮之间的三键。
Clearly, we put 2 for each bond, and now we end up having 2 remaining bonding electrons left.
显然,我们在每个键处放上两个电子,那么最后我们还剩下两个成键电子。
For the sulfur, we start off with 6 valence electrons, minus 4 lone pair electrons, minus 2, taking in account our bonding electrons, so we end up with a formal charge of 0.
对于硫,我们从六个价电子开始,减去四个孤对电子,再减去二,算上我们的成键电子,因此最终我们有零个形式电荷。
So, we end up with a total of six electrons that are possible that have that 2 p orbital value.
所以我们最后,总共得到了6个电子,在所有可能的“2p“轨道值中。
px 2py So we need to fill all the way up to the pi 2 p x, and the pi 2 p y.
我们需要填到。
Even the game, when you chose numbers, you chose numbers 1, 2, 3, 4, 5, up to a 100, there were 100 strategies.
比如那个数字游戏,你能从1到100这100个数字中选择
So we end up having 2 orbitals here.
所以我们得到2个轨道。
Suppose Firm 2 has produced all of this quantity up to here.
假设公司2产量一直提高到这里
So, in this program when we call this version of swap 1 and 2 do not end up here, right?
所以,在这个程序中,当我们调用这个swap版本1,和版本2,不是在这里结束,对不?
If we look at our last structure here where we have nitrogen the middle, we can also figure out all those formal charges, and in this case we have plus 1 on the nitrogen, we have minus 2 on the carbon, and then we end up with a 0 on the sulfur there.
如果我们来看看最后一个结构,在中间的原子是氮,我们同样可以计算出所有的形式电荷,而在这种情况下,氮为正一,碳为负二,而最后硫为零。
As reported contemporaneously in 2000,the number was -3.1% but if you look at the number reported for 2005, because bad records had disappeared and good records had been added, all of a sudden the average experience for that year went up to +1.2%.
000年期的公告中这个数字为负3.1%,但是如果你去查2005年公告的数字,坏记录已经调整而消失,有利的投资记录被加入,转瞬之间,年平均收益升至1.2%
There's no more 2 p orbitals to put it into, so we're going to actually have to double up.
现在并没有多余的2,p,轨道来放它,我们只能在其中一个,2,p,轨道上放上两个。
So I wanted to take a few excerpts from the course's syllabus since it's not an interesting document to walk through line by line, but something you should read at some point very is not so much where you end up relative to your classmates 2 but where you end up in week 12 relative to yourself in week 0.
我想从教学大纲中,挑几段来讲一下,逐字的阅读虽然没趣,但是你也应该在某些点注意一下,你跟你同学相比最终如何,而是当第12周的时候相比第0周2,你的收获如何。
