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) + 2HCl (aq) -> XCl2 (aq) + H2(g)
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
By looking at the reaction, it somewhat seems it is a group 2 metal e.g. Mg. Magnesium reacts with hydrochloric acid according to the equation: Mg(s) + 2 HCl(aq) --> MgCl2(aq) + H2(g) This demonstration can be used to illustrate the characteristic reaction of metals with acid, a single replacement reaction, or to demonstrate the generation of hydrogen gas.The ionic compound formed will be MgCl2 which will have ionic bonding.

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.
