Read the following chemical reaction:
Na2S + 2HCl → 2NaCl + H2S
Which of the following statements best describes the reaction?

This reaction is a double replacement reaction because Na switched places with H and not a redox reaction because the ion charges of the elements remained the same.

This reaction is a double replacement reaction because Na switched places with H and a redox reaction because the ion charges of the elements changed from a 0 charge on Na to +1 charge, and a +1 charge on H to a 0 charge.

This reaction is a single replacement reaction because Na switched places with H and not a redox reaction because the ion charges of the elements remained the same.

This reaction is a single replacement reaction because Na switched places with H and a redox reaction because the ion charges of the elements changed from a 0 charge on Na to +1 charge, and a +1 charge on H to a 0 charge.
