Question

balance the following redox reaction : TlO3 + NH2OH----->TlOH+N2 can someone please explain this tooo me. I got to elements thats are reduced. :(

Answer 1

do you know how to assign oxidation states?

Answer 2

yes you mean oxidation numbers

Answer 3

haha yeah thats what i mean. Are you balancing by a certain method? i only know the half reaction method

Answer 4

yes that one . AND IM CLUELESS , i thought i gripped the concept but now im lost !!!!

Answer 5

so you assigned oxidation numbers to everything? what did you get?

Answer 6

for Tl i got -3
O3 = -2
N=-1
H2= 1
O= -2
H=1
thoses are the reactants
the products i got
Tl = 1
O= -2
H= 1
N2= 0
is that right ???

Answer 7

oh god why would you write it like that..

(+6)(-6) (-1)(+2)(-2)(+1) (+1)(-2)(+1) 0
TlO3 + NH2OH-----> TlOH + N2

so you got the TlO3 wrong

Answer 8

sorrry :(

Answer 9

haha it's cool, it's just more confusing

Answer 10

i couldnt think of another way Lol i was caught up in this problem

Answer 11

Sorry it should be like this:

(+6)(-2) (-1)(+1)(-2)(+1) (+1)(-2)(+1) 0
TlO3 + NH2OH-----> TlOH + N2

Answer 12

ok , ok iget it so Tl is oxided and N is reduced right

Answer 13

thank you soo much

Answer 14

wait im soo sorry it should be Tl2 for the reactants

Answer 15

im soo sorrry
its my fault
i forget the 2 when i typed it

Answer 16

it's actually the other way around..

Tl (+6) -> Tl (+1)
N (-1) -> N (0)

Answer 17

ok im soo smart lol

Answer 18

reduction is the gain of electrons.. meaning going more negative

Answer 19

haha getting there !

Answer 20

hehhe what are you implieing im dumb! lol

Answer 21

haha nono

okay so you're saying it should be Tl2?

Answer 22

yes

Answer 23

i was only joking btw

Answer 24

lol same here...


(+3)(-2) (-1)(+1)(-2)(+1) (+1)(-2)(+1) 0
Tl2O3 + NH2OH-----> TlOH + N2


like that?

Answer 25

do you know what to do next?

Answer 26

ok then u write the half life of the ones that are oxided and reduced

Answer 27

and you balance the number of electrons transferred

Answer 28

is this in acidic or basic medium?

Answer 29

yes its basic ?

Answer 30

so once you balance the number of electrons balance the charges with OH-

then balance the number of O's and H's with H2O

Answer 31

capiche?

Answer 32

for Tl2 i made it negative instead of positive , that why i got to reduced
elements

Answer 33

capiche my friend :)

Answer 34

ohh okay, well at least you got where you went wrong.

if you get stuck again, just ask !

Answer 35

dont worry i wont hestatiate to ask. Ur soo nice

Answer 36

listen i hate ap chem and im pretty sure i will have tons of questions lol

Answer 37

haha okok

Answer 38

ok ok
