Choose an expression for the acid ionization constant (Ka)(Ka) for HFHF. Choose an expression for the acid ionization constant for . Ka=[H3O+][F−][HF]Ka=[H3O+][F−][HF] Ka=[F−][H3O+][HF]Ka=[F−][H3O+][HF] Ka=[HF][H3O+][F−]Ka=[HF][H3O+][F−] Ka=[H3O+][HF][F−]Ka=[H3O+][HF][F−]

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.

the answer is c. nacl
