do you kno @Bozhena

Answer 9

d

Answer 10

Which of the following describes an element that is reduced in a reaction?

It acts in the reactant that is the reducing agent.

It has a decrease in its oxidation number.

Cd yields Cd2+ + 2e−

Zn + Cu2+ yields Zn2+ + Cu

Answer 11

@Bozhena what about this

Answer 12

@blackeistien238821 do you kno

Answer 13

Red is when an elment GAINS e'.

So if you have Cd yields Cd2+ + 2e−
It means that Cd ox.n 0 passed to Cd++ ox.n +2. When you see + it means atom had something less, in this case he had 2è less than Cd 0. So Cd++ GAINS two electrons and become Cd 0.

Answer 14

Try to do the next reaction

Answer 15

so the answer would be a?

Answer 16

@Bozhena

Answer 17

you tell me.
If an element get reduced whan it gains electrons, and i told you that Cd++ gains two e' to get Cd.

Answer 18

so which is correct b?

Answer 19

@Bozhena

Answer 20

both
Cd and Zn get reduced.

Answer 21

so the answer would be?
