Question

MEDAL, please help me understand.
Which best describes the oxidizing agent in this reaction?
Cl2(aq) + 2Brmc003-1.jpg(aq) mc003-2.jpg 2Clmc003-3.jpg(aq) + Br2(aq)
Bromine (Br) is the oxidizing agent because it gains an electron.
Bromine (Br) is the oxidizing agent because it loses an electron.
Chlorine (Cl) is the oxidizing agent because it gains an electron.
Chlorine (Cl) is the oxidizing agent because it loses an electron.

Answer 1

oxidizing agents force \(other \space atoms\) or ions to be oxidized. If you force someone else to be oxidized, what must happen to you?

Answer 2

you would need to losse an electron, right?

Answer 3

oxidation is the loss of an electron.

Answer 4

If I'm going to force you to be oxidized, that mean I'm going to make YOU lose an electron

Answer 5

(that means I'm going to take it)

Answer 6

so i would loose one, i dont really understand how u gain and loose them

Answer 7

if you lose your electron, that means I must take it

Answer 8

so you get oxidized, and I get reduced

Answer 9

so if bromine is the oxidized agent then its lossing an electron because you would be taking one away from it

Answer 10

no, the oxidizing agent forces the OTHER one to be oxidized

Answer 11

okay so it would be down to A or C since it would gain the electron if it takes it

Answer 12

if the \(2Br^{-1}\) loses the electron to become \(Br_2\), then the bromine has been oxidized. Who was the oxidizing \(agent\)?

Answer 13

chlorine

Answer 14

right.

Answer 15

the oxidizing agent is the one who \(gets\) reduced.

Answer 16

okay thank you, can you help me with another?

Answer 17

sure

Answer 18

Given the reaction below, which is the reduced substance?
Mg + Cl2 mc006-1.jpg Mg2+ + 2Clmc006-2.jpg
2CI-
CI2
Mg
Mg2+

Answer 19

same question

Answer 20

the first image thing is an arrow (----->) and the second one is a negitive sign

Answer 21

"which is the reduced substance"

which substance gets reduced?
which substance GAINS electrons?

Answer 22

i dont understand where the 2 infront of Mg came from and what it stands for

Answer 23

the reaction should look like this\[Mg + Cl_2 \rightarrow Mg^{+2} + 2Cl^{-1}\]

Answer 24

yea so would Cl be the reducaed substance since the 2 after it is no longer there?

Answer 25

which reactant gains electrons?

Answer 26

Mg

Answer 27

the magnesium starts with a neutral charge and ends with +2. Is gaining electrons the way to gain positive charge?

Answer 28

no it would have to be reduced to take them from other things, right?

Answer 29

yes, which reactant GAINS electrons?

Answer 30

chlorine

Answer 31

it is
