    Teacher: explains half equations for the third time
    Me: I don't get it
    Machemguy: speaks for 30 seconds
    Me: oh that makes sense now!

    You have literally turned my life around machemguy! I was struggling with chemistry at the start of this year getting D's/E's in my mocks. After watching your videos and some hard work, I just achieved an A in my recent mock! Thank you so much for the making these videos

    Please do a video on more complicated balancing equation questions. Such as when you aren't given the half equations or when you are given the full equation and one half equation and asked to find the other half equation, some of the past paper questions are horrible!

    Hello,
    I have a quick question(s): If I had an even number of H+ on both sides of the equation could I just cancel them out?
    Another problem that I have is that I can vaguely remember watching somewhere that H+ can be taken over to the other side of an equation to join another H+. Consequently the number of H+ will reduce because taking the H+ will change the sign to a negative? Is this correct? And if so which side will it go to? I'm assuming the smaller number of H+ will join the larger number on the opposite side? If they were originally on the same side I just add them up like like terms in maths?
    I hope I have explained my question clearly and I thank you in advance for taking time to answer it.
    Thanks,
    Salsabil

  • @OuchMyWristHurts
    @OuchMyWristHurts 9 лет назад +1

    Hi there, just about the point you made where we should only add H+ or H2O, I seem to remember comming across questions where under basic conditions you would need to add OH- ions, how would you go about balancing this kind of question?

    This was really helpful thank you. But what one question I didn’t understand was the last one if there were 8 hydrogens on the right side shouldn’t you add 6 hydrogen ions on the other side because the H2S04 already has two hydrogens. Thank you

  • @tryingtolearnn

    I don't get why it can't be 3+ oh the lhs because each CR is ^+ on LHS and on 3+ on RHS so 6-3=3

    • @MaChemGuy
      @MaChemGuy  Год назад +1

      If you’re referring to the second example, it’s says it’s in acidic conditions so we use H+ ions
