    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

    • @TheOrganicChemistryTutor
      @TheOrganicChemistryTutor  8 років тому +7

      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 :)

    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.

    • @pinkmingo33
      @pinkmingo33 7 років тому +6

      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 :)

    • @asadshahbukhari8928
      @asadshahbukhari8928 6 років тому +6

      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

    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

    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)

    • @noxrox1994
      @noxrox1994 5 років тому

      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).

      @henryelicker2403 5 років тому +2

      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.
