    The z and 2 looking the same is not okay

    would it not be 2LiOH(little 2)?

    If you do not subscript H in the answer you only have 3 hydrogen in the equation and you need 4 right?

    2liOH will be correct

    Put a 2 in front of LiOH

    Erm… I'm pretty sure Li will NOT displace Na from NaCl given that Na is more reactive that Li. Periodicity tells us that for group 1 elements, reactivity increases down the group and since Na is below Li, Na is more reactive. Hence Na will displace Li from LiCl but not the other way around. Correct me if i'm wrong.

    how would we know if that element is more active than the other to be replaced?

    Balanced equation is 2Li+2H₂o->>> H₂+ (2) LiOH    You would add the 2 infront of LiOH to balance it. Am I right. I am sure of it

    What would C7H6O2 + O2 equal?

  11. alexa mouse879 Avatar

    would Zn + HCl = ZnCl + H?

    2LiH(2)O -> 2HLiOH

    funny how the lesson 10(?) about quantum mechanical formula is waaay harder than all of this stuff …

  14. Rolando Medina Avatar

    it was 2..
    way too easy

    Wouldnt it be 2 infront?

    Li = 2, O = 2, H = 4. Since we already have H2, we still need 2 more for H to be 4, so the answer is 2LiOH. 😀 Lol, I suck at explaining but oh, well.

    Put a horizontal tick mark through the middle of your letter Z.

    the anser is 2Li

  19. Von Nabo Avatar

    2Li+2H2O-> H2+2LiOH

  20. Gretchen Graef Avatar

    Put a horizontal line through your Zs to distinguish them from 2s.

    to know which one is more reactive, you need to understand more basics of the periodic table, watch khan academy chemistry videos 4-9 to understand periodic table more clearly,, bucky is still better.

    Someone saying 'L O L' makes me lol, in a way that makes me die a little inside. Which I find funnier than the actual post 😉

    BUT, in all fairness, this was very helpful 🙂 Good job.
