Answer 2

Compounds with Ionic Crystal Lattices:

Among the given compounds, the following substances have ionic crystal lattices:

1. KCl (Potassium Chloride) - KCl is an ionic compound composed of potassium cations (K+) and chloride anions (Cl-) [[1]]. 2. AlCl3 (Aluminum Chloride) - AlCl3 is an ionic compound composed of aluminum cations (Al3+) and chloride anions (Cl-) [[2]]. 3. BaO (Barium Oxide) - BaO is an ionic compound composed of barium cations (Ba2+) and oxide anions (O2-) [[3]]. 4. Fe2O3 (Iron(III) Oxide) - Fe2O3 is an ionic compound composed of iron(III) cations (Fe3+) and oxide anions (O2-) [[4]]. 5. Fe2(SO4)3 (Iron(III) Sulfate) - Fe2(SO4)3 is an ionic compound composed of iron(III) cations (Fe3+) and sulfate anions (SO42-) [[5]]. 6. H2SO4 (Sulfuric Acid) - H2SO4 is a covalent compound in its molecular form. However, when dissolved in water, it dissociates into ions, making it an electrolyte [[6]].

Compounds with Other Types of Bonding:

The remaining compounds have other types of bonding:

1. C2H2ONa (Sodium Acetate) - C2H2ONa is an organic compound that consists of covalent bonds between carbon, hydrogen, and oxygen atoms. It does not form an ionic crystal lattice [[7]]. 2. SiO2 (Silicon Dioxide) - SiO2 is a covalent compound that forms a network of covalent bonds between silicon and oxygen atoms. It does not have an ionic crystal lattice [[8]]. 3. NH3 (Ammonia) - NH3 is a covalent compound that consists of covalent bonds between nitrogen and hydrogen atoms. It does not form an ionic crystal lattice [[9]].

In summary, compounds like KCl, AlCl3, BaO, Fe2O3, and Fe2(SO4)3 have ionic crystal lattices, while compounds like H2SO4, C2H2ONa, SiO2, and NH3 have other types of bonding, such as covalent bonding.
