Question

In the chemical reaction shown below, which element was oxidized?

4Fe + 3O2 yields 2Fe2O3

Fe, because it gained 3 electrons

Fe, because it lost 3 electrons <--?

O, because it gained 2 electrons

O, because it lost 2 electrons

Answer 1

4Fe + 3O2 ---> 2Fe2O3

Answer 2

OIL RIG = Oxidation is loosing electrons, Reduction is gaining electrons.
Now what do you think?

Answer 3

Wouldn't it be B? Or since you said that it might be D

Answer 4

ohh

Answer 5

i think c now

Answer 6

It's actually "Fe, because it lost 3 electrons"

You have to figure out the oxidation numbers of each element, then look at what happened in the reaction in the products.

Answer 7

Yup, good job.

Answer 8

wait so it's b or c haha

Answer 9

B
