The z and 2 looking the same is not okay
-
2 LiOH
-
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?
-
2LiON
-
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?
-
would Zn + HCl = ZnCl + H?
-
*(Subscript)
2LiH(2)O -> 2HLiOH -
funny how the lesson 10(?) about quantum mechanical formula is waaay harder than all of this stuff …
-
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
-
2LiOH
-
2Li+2H2O-> H2+2LiOH
-
Put a horizontal line through your Zs to distinguish them from 2s.
-
2 LiOH
-
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.

X=2

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.
