What is your nucleophile and what is your substrate?

i know that the nucleophile attacks the electrophilic carbon (on the substrate) and forces the leaving group to leave, i am just not sure which is which

You have 3 substances: Ethyl chloride, Sodium ethanoxide, Ethanol.
Negative-charged oxygen (-OCH2CH3) of sodium ethanoxide must attack alpha-carbon, that is a carbon atom next to Cl, of ethyl chloride in the ethanol as solvent.

The attacking group is CH

O

and it displaces Cl

from the compound. Cl

being a good leaving group cleaves immediately. The substrate also undegoes Walden Inversion. The product being CH

, i.e. ethoxy ethane.Alcohol acts as a non-polar solvent.

The SN2 reaction and E2 reation sometime make you wrong. This reaction can make di ethyl ether or propene,depend on your catalysis.
