The answer is the third choice because is oxidation half reactions, only the oxidation state of the reducing agent changes; in this third choice, Fe2+ is oxidized and becomes Fe3+. Just keep in mind that half reactions usually include the change in electrons:
Fe2+ -> Fe3+ +e-<span />
The ball and stick model of C subscript 2 H subscript 4 is described as Option C: Each C has 2 H's connected to it each by 1 black.
This means the same as the 3D structure image of ethylene (C2H4) and means 2 C's connected by 2 black lines.
line.
The structure of ethylene is made up of 2 carbon atoms and 4 hydrogen atoms.
The carbon atoms are located at the middle position and the hydrogen atom surrounding the carbon atoms with two hydrogen atoms connected to each carbon atom. The two black lines connecting the carbons are the double bonds.
