Oxidation - Reduction Chapter Quiz / Review :)
Settings
I am going to use this Quiz to see if you fully understand the topic of Oxidation and reduction. you are gonna take this quiz after my presentation. . . Its easy trust me. afterwards, I will grade each one of you out of 100. Good Luck! :)
- 1.
- A.
Oxidation- the loss of electrons by atom or ion/ the gain of oxygen, Reduction- the loss of oxygen/ the gain of said electrons.
- B.
Oxidation- the gain of electrons by an atom or ion/ loss of oxygen, Reduction- the gain of oxygen/ the loss of electrons by atom or ion.
- C.
Oxidation- something having to do with oxide, i don't care -__- Reduction- something's being reduced, but i don't know what.
- 2.Can oxidation and reduction occur without one another?
- A.
They are interdependent
- B.
They are not interdependent.
- 3.
- A.
Its a combination of Reduction and Oxidation, when one occurs, the other does not.
- B.
It is not a combination of reduction and oxidation , when one occurs, the other must occur as well.
- C.
Its a combo of both REDuction and OXidation. one reaction cannot occur without the other.
- 4.
- A.
LEO- Loss of Electrons is Oxygen, GER- Gain of Electrons is Red
- B.
LEO- Loss of Elections is Oxidation, GER- Gain of Electrons is Reduction
- C.
LEO- Loss of Electrons is Oxidation, GER- Gain of Electrons is Reduction
