Which represents a double replacement reaction and would occur? NH4NO3(aq) + AgCIO3(aq) → AgNO3(aq) + NH4CIO3(aq)

Na2CO3(aq) + CaCl2(aq) → 2NaCl(aq) + CaCO3(s)

NaF(aq) + KCl(aq) → NaCl(aq) + KCl(aq)

NaCl(aq) → Na+(aq) + Cl-(aq)

The correct answer is B . Na2CO3(aq) + CaCl2(aq) → 2NaCl(aq) + CaCO3(s)

Explanation:

hope it works out !!

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.
