Answer 1

#taramgrant0543664 help please

Answer 2

I'm sorry I can't see part of the reaction it's up a little high and too much too the right, I'm on my iPad so it likes to be difficult
I see CuO+H2-->Cu +
That's all that I see
I'm assuming if I have the reactants right it should be
CuO+H2 --> Cu+ H2O

Answer 3

yes

Answer 4

So when dealing with redox reactions most people have a saying that helps them remember mine is LEO the lion says GER
LEO meanings lose electrons oxidized
GER meaning gain electrons reduced
For this question we need to determine which one loses electrons to become oxidized

Answer 5

CuO + H2 --> Cu + H20
We need to figure out the charges on each of the elements
(+2)(-2)..(0) -->(0)..(+1)(-2)

Answer 6

As you can see oxygens charge remains at -2 so oxygen is neither oxidized or reduced

Answer 7

Cu goes from a charge of +2 to 0
H goes from a charge of 0 to +1
Which one is losing electrons?

Answer 8

cuo+h2 right

Answer 9

The element that is oxidized is the one that loses electrons so it becomes more positive

Answer 10

ok

Answer 11

Cu goes from a charge of +2 to 0
H goes from a charge of 0 to +1
One is gaining electrons and therefore reduced
One is losing electrons therefore oxidized
