Household ammonia solution (primarily NH3) accidentally spills onto a countertop that was just cleaned with vinegar (aqueous CH3COOH). Which net ionic equation represents the dominant acid–base process that occurs on the surface?
a) NH4++CH3COO−→NH3+CH3COOH
b) No reaction occurs because both substances are weak and remain unreactive.
c) NH3+CH3COOH→NH4++CH3COO−
d) NH3+CH3COOH→NH4++CH3COOH
