Which chemical equation represents the reaction of an arrhenius acid and an arrhenius base?
(1) hc2h3o2(aq) + naoh(aq) --> nac2h3o2(aq) + h2o(l)
(2) c3h8(g) + 5 o2(> 3 co2(g) + 4 h2o(l)
(3) zn(s) + 2 hcl(> zncl2(aq) + h2(g)
(4) bacl2(aq) + na2so4(aq) --> baso4(s) + 2 nacl(aq)

i think that is the right

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.
