Question

Balance the following equation in acidic conditions.

Cr2+ + H2MoO4 --> Cr3+ Mo

Answer 1

Alright so the goal of balancing is to get the same amount of elements on each side right?

Answer 2

yes

i put Cr2+ + H2MoO4 +6H+ +5e- --> Cr3+ Mo+4H2O and got it wrong :(

Answer 3

omg, no offense but ur dp looked like justin bieber... did anyone tell u that? sorry, just had to say it

Answer 4

Look at the Cr

Answer 5

yeah
the 2+ is the charge

Answer 6

And errr, gotta look closely :P

Answer 7

lol idk but the charge is diff on the other side

Answer 8

Cr2 is on one side while Cr3 is on the other, find a common multiple.

Answer 9

6

Answer 10

ooh! do i multiply each side by 6 or just that Cr ion

Answer 11

well i mean 2 and 3 on the appropriate side

Answer 12

so you gotta multiply each Cr by a number to get 6.

Answer 13

Yeah

Answer 14

mmk, is that the only thing?

Answer 15

is the rest of it OK?

Answer 16

I guess, I don't have chemistry until next semester. So I wouldn't know how to balance in acidic conditions.

Answer 17

oh, wow.. u dont have chem n u knew this? lol smarter than me then! but thank u!

Answer 18

Lol i guess :P

Answer 19

i had like 2 more questions (n i know u said urnt in chem) but can u take a look @ em?

Answer 20

I gotta study for physics. Are they urgent?

Answer 21

uhh yeah like less than an hour before the hw closes
and aww i got it wrong! like i put a 6e- on the left side (instead of 5e-)

Answer 22

ill put em on here (it'll take a while cuz i gotta type em) n then can u just glance @ em and see if u have any tips for solving em

Answer 23
