Section 20.1 the meaning of oxidation and reduction answer key

Oxidation is defined as the reaction in which there is loss of electrons. It  is accompanied by increase in oxidation number.

Fe being the pure element in its standard state has oxidation number of zero and on loosing electron changes to oxidation number of +2.

Reduction is defined as the reaction in which there is gain of electrons. It  is accompanied by decrease in oxidation number.

Iron changes from oxidation number of +2 to pure iron [Fe} with oxidation number of zero.

thats a little if u want the answer just look it up on google thats what i do haha : )

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
