Name each of the following species for the following acid-base reactions. (The equilibrium lies to the right in each case, i.e., the product side is favored. If the species is an ion, include the word "ion" in the name. Use systematic names such as "methanol" instead of archaic names like "methyl alcohol" or "wood alcohol".)
a. CH3CH2O- (ethoxide ion) + H3O+ (hydronium ion) <->
b. HBr (hydrogen bromide) + CH3O- (methoxide ion) <->
c. NH2- (amide ion) + CH3OH (methanol)
