The equation shows the reaction between element X and dilute hydrochloric acid. What types of bonding are present in element X and in compound XCl2? X(s) + 2HCI(aq) → XCI(aq) + H2 (g)
Correct answer: D. Metallic, Ionic
- A. Covalent, Covalent
- B. Covalent, Ionic
- C. Metallic, Covalent
- D. Metallic, Ionic
Explanation
Since hydrogen is released, we can assume that X is an electropositive element, almost surely a metal, so X will have metallic bonding. For the next part, since X is a metal, XCl will have ionic bonding since almost all metal compounds form ionic bonds and not covalent.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
