Final answer:
The reaction MgCl₂ + NaF → NaCl + MgF₂ is an example of a double displacement reaction, where the positive and negative ions of two compounds switch places, resulting in the formation of two new compounds.
Step-by-step explanation:
The reaction MgCl₂ + NaF → NaCl + MgF₂ is an example of a double displacement reaction. In a double displacement reaction, the positive and negative ions of two compounds exchange their places, which results in the formation of two new compounds. In this case, the magnesium ion (Mg²⁺) from magnesium chloride (MgCl₂) reacts with the fluoride ion (F⁻) from sodium fluoride (NaF), and the chloride ion (Cl⁻) from magnesium chloride reacts with the sodium ion (Na⁺) from sodium chloride (NaCl), resulting in the formation of magnesium fluoride (MgF₂) and sodium chloride (NaCl).
