The answer is A, the contras x Good luck!! :)
C2H4 is oxidized and O2 is reduced in both reactions.
<h3>What is oxidation/reduction?</h3>
Oxidation is defined in several ways. Some of the definitions are:
- The addition of oxygen or removal of hydrogen
- Increase in the oxidation number of atoms
- Addition of electronegative or the removal of electropositive elements
Reduction, on the other hand, is defined as:
- Removal of oxygen or addition of hydrogen
- Decrease in the oxidation number of atoms
- Addition of electropositive elements or the removal of electronegative elements.
In the two reactions, oxygen is being added to C2H4. Thus, C2H4 is being oxidized.
The oxidizing agent is O2. In oxidation reactions, the oxidizing agents usually get reduced. Thus, O2 is reduced in both reactions.

C = 4 mol/l
v = 0.5 l
n(NaCl)=cv
n(NaCl) = 4 mol/l · 0.5 l = 2 mol
2 moles of NaCl must be dissolved
Answer:
A is the answer
Explanation:
See, let me explain it first of all.
Because, We all know every drop of water is being evaporated from the seas, streams, oceans,etc. So, the statement is wrong about it. It is wrong. How can't water get evaporated from the seas and the streams,etc.
I wish you got a helping hand from me. If it helps don't forget to like and mark me
Sr(NO3)2 ---> Sr²⁺ + 2 NO3⁻
from the reaction 1 mol 1 mol 2 mol
from the problem 0.5 mol 0.5 mol 1 mol
