Question

Could someone help me figure this out?

Answer 1

I'm supposed to tell which element was reduced and which was oxidized but I don't know how to find that.

Answer 2

well look at elements on reactant side and compare with product side

Answer 3

if something is Oxidized - it Loses electron
if something is Reduced it Gains electron

Answer 4

OIL RIG
Oxidation is Loss
Reduction is Gain
best way to remember

Answer 5

so would the Oxygen be oxidation

Answer 6

nope
Oxygen was -2 before reaction occurred and stayed as -2 after reaction

Answer 7

Redox

Answer 8

My brain hurts. I've been doing chem and algebra all day so now I'm really confused, I was on a role too.

Answer 9

Don't get this so much series,,get some rest,, this is not that much harder,,,, :)

Answer 10

Oh serious :)

Answer 11

Now your answers are right,,, @somy

Answer 12

@asib1214 :-)

Answer 13

I have a deadline though to reach, which gives me no time for breaks.

Answer 14

Well
you do know about oxidation states as i see
+ means it looses
- means it gains
example
change from +2 to +3 -means something lost 1 more electron
change from +2 to +1 - means something gained 1 electron

change from -2 to -3 - means something gained 1 electron
change from -2 to -1 - means something lost 1 electron

Answer 15

I feel as if Aluminium is the one that lost electron.

Answer 16

as well as
change from 0 to -1 - means gains 1 more electron
change from 0 to +1 - means lost 1 electron

Answer 17

Bingo!

Answer 18

does that mean it's oxidized?

Answer 19

yup yup

Answer 20

and the hydrogen atom was reduced?

Answer 21

yup yup

Answer 22

Al
changed from 0 to +3
meaning lost 3 electrons - thus Oxidized
H
changed from +1 to 0
meaning gained 1 more electron - thus Reduced

Answer 23

I see, thank you very much. You were very informative and helpful.

Answer 24

you are welcome :3

Answer 25

such accuracy @Somy

Answer 26
