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。
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。
So the correct answer for titanium plus two Ar3d2 is going to be argon 3 d 2, whereas if we did not rearrange our order here 4s2 we might have been tempted to write as 4 s 2 so keep that in mind when you're doing the positive ions of corresponding atoms.
所以正2价钛离子,的正确答案是,然而如果我们不重新安排顺序,我们可能会写出2,所以请记住,它当你们在解关于原子,的正离子的时候。
This is titanium sponge that comes out of the bottom of this reactor, and it subsequently re-melted in a vacuum arc furnace.
海绵状的钛,从反应器的底部出来,随后在真空炉中重新熔炼。
So, as these products form, they continue to fall out of the way and keep this interface open.
因此随着产物的生成,金属钛会下沉,使得界面仍然保持开放。
And at the end of the reaction, you have the reactor consumed of titanium tetrachloride magnesium.
在反应的结尾时,反应器里面,消耗了四氯化钛和镁。
And then, that produces 515 moles titanium.
嗯,就是产生了515摩尔的钛。
And, these are giant billets of solid titanium weighing tens of tons.
这些巨大的固体钛的铸锭,有十几吨。
And so, for that, I want to look at the production of titanium by the Kroll process.
因此而言,我想看看克劳尔法,制备钛的工艺。
And, this is a really clever reaction because titanium tetrachloride is a gas.
这是一个非常巧妙的反应,因为四氯化钛是一种气体。
While he was still in Luxembourg, just before World War II broke out, he emigrated to the United States and finished his career in the Pacific Northwest where he helped make huge quantities of titanium.
他一直住在卢森堡,在二次世界大战爆发前,他移民到了美国,后半生在太平洋西北部,他制备了大量的钛结束了他的事业。
So, for example, if we needed to figure out the electron configuration for titanium, 4s2 it would just be argon then 4 s 2, 3d2 and then we would fill in the 3 d 2.
所以举个例子,如果我们需要解出钛的电子构型,它会是Ar然后,然后我们填充。
I can only make as much titanium as is consumed by the available magnesium.
有多少可以被消耗的镁,就能得到相应的钛。
So, how much titanium can I make?
我能制出多少的钛呢?
And then I convert that to mass, and that gives me 24.7 kg of titanium.
换算成质量,就是24。7kg的钛。
OK, so let's say some young engineer is on the job the first day and says, OK, let's put in 200 kg of tickle, and let's put in about 25 kg of mag.
比如一些年轻的工程师,刚来上班时会说,投入200kg的四氯化钛,投入25kg的镁。
I don't care how you do it on exams or on problem sets, but you do need to be aware that the 3 d once filled is lower in energy than the 4 s, and the reason you need to be aware of that is if you're asked for the electron configuration now of the titanium ion.
我不关心你们在考试或者,问题集中如何做它,但是你们的确需要知道3d一旦被填充,它的能量是小于4s的,你们需要知道这个的原因,是如果你现在被要求,写出钛离子的电子构型。
