Hello. Thanks for the video as it is very good. Just finished this video and can you please check the solutions to these... 1:56:54 -- Should the answer have been 2 instead of 22 and 2:20:00. Should the calculation have been done using S and not S8 as the number of moles given were for sulphur but then you asked for grams of S8. so in that in case we should calculate grams of S and then multiply times 8 to get the right the answer, which would give an answer of 127.79... please advise thanks a lot for your time in making the video
Thanks for the first correction. It should be 2 instead of 22. As for the second part, the mass of sulfur will be the same. if you divide 3 x 10^23 atoms of S by 6 x 10^23, you get 0.5 moles of S atoms. If you convert it to molecules of S8 by multiplying 0.5 moles of S atoms with 1 mol of S8 / 8 mol of S, you get 0.0625 mol of S8. If you convert 0.0625 mol of S8 into grams by multiplying it by 256g of S8 / 1 mol of S8, this will give 16g of S8 or 16 grams of sulfur. If you convert 0.5 moles of S into grams by multiplying it by 32g of S / 1 mol of S, you will still get 16g of sulfur. Either case, the mass of sulfur is still the same. I hope that helps :)
Thanks for this! Great to listen to during commute so that time isn't wasted :) Question: At 26 min, you state that metals, when heated, decrease in electrical conductivity. However metalloids, when heated, increase in electrical conductivity. The first statement seems counterintuitive - would you mind explaining? I don't recall learning this.
I've been looking into this - it seems as if as metals are heated, the number of electronic collisions increases, which impedes electrical conductivity. For metalloids, I haven't found much info. But I could make an educated hypothesis that since they have fewer free electrons for conduction purposes, the increased collisions effect is less dramatic. If anyone else has further input, please add :)
actually with the increase in temperature, vibration of metal atoms is increased which narrows the passage of moving electrons in conductors, so with increase in temperature, resistance is increased in it.. however, in semi conductors, case of conduction is a little different.. if you recall the energy band theory then you can see that with the increase in temperature, more electrons jump into the conduction band from the valence band, so it's conductivity is increased!! that was a simple and brief answer to your question

looked in the kaplan mcat for chemistry and just do not function as a textbook as my sole source. typed in mcat chemistry review and look what I see, 6 hours total of chemistry with org tutor... you bet your ass Im in!
LOL. I didn't know there was such a small amount of chem in medicine. Maybe that explains why my GP looked in awe when I told him I teach chem, then I glanced at his brag wall saying, "Dude, you're an MD!". Nice respect all around, but come on. Being an MD is a much harder course of study. Good luck to all of you.
Oh man... Why so many ads??? I really find useful your vids and I thank you! It's just, the interruptions can be quite disturbing. Other than that you're great 😉🙃
3:18:59 I am struggling with the empirical formula question. I don't see why you can figure that for every 2 hydrogens in H20, there is one hydrogen in the hydrocarbon. You use this 1mol H20 :2 mol H ratio to get the empirical number for hydrogen. We don't know the balanced equation, because there could be one or two hydrogens on the left side of the equation, or as many as ten so it would be wrong to assume that the ratio is 1:2
Thank you so much for these videos. I know this is a very very long shot. Do you do tutoring on wyzant or do private communications. Thank you so much for what you have done. If there is a way to reach out i would greatly appreciate it
Hello, is this the full video of Gen Chem review? I see there is a part 2 as well. So total of 6 hours should cover all of the topics you have listed in the description? Thanks.
7:03 every thing with more than one element or two of the same element bonded together is a molecular compound? but then there is covalent compounds like H2O and ionic compounds like NaCl. I think you set that chart up wrong.
I admire what you are doing but I'm taught that all noble gases are monoatomic molecules but that goes against what you told here in this video can you explain that.
Sorry I'm a little late here, but to the best of my knowledge of chemistry I hope this helps. Any binary ionic (or any ionic compound) formed by an anion and a cation is considered just a "compound" or "ionic compound", such as sodium chloride (table salt) or magnesium oxide. Any compound that is covalently bonded is considered a molecule, such as glucose, n-hexane, 2,2-dimethlybutane to name a few. Hope this helps. Note: the "n" in n-hexane denotes the compound hexane is normal and distinguishes it from an isomers, which are the same molecular formula but the atoms are differently connected.
It wouldn't be because of the way the problem is set up. AMU = m1*p1 + m2*p2 10.81 = 10(x) + 11(1-x) Since (1-x) is in the parenthesis... you would first have to do 11*1 = 11 and then 11*(-x) = -11x. So the next part, what he does is he puts the like terms together which is where I think you might've gotten confused. Therefore: 10.81 = 10x + 11 - 11x 10.81 = -1x + 11 (You're putting -11x + 10x which equals -1x. So it wouldn't be 11-(-x).... it's just simply 11 - 1x).

46:40 you said it should be -1x but then put 11-x, what happened to the negative in front of the x? Shouldn’t it be 11-(-1x)
It wouldn't be because of the way the problem is set up.
AMU = m1*p1 + m2*p2
10.81 = 10(x) + 11(1-x)
Since (1-x) is in the parenthesis... you would first have to do 11*1 = 11 and then 11*(-x) = -11x.
So the next part, what he does is he puts the like terms together which is where I think you might've gotten confused. Therefore:
10.81 = 10x + 11 - 11x
10.81 = -1x + 11 (You're putting -11x + 10x which equals -1x. So it wouldn't be 11-(-x).... it's just simply 11 - 1x).
