Witryna21 lip 2024 · Molecules that contain non-polar multiple bonds make Lewis bases. Molecules in which the central atom expands due to its empty d-orbitals e.g. FeCl 3 are Lewis acids. All metal oxides that have no d-orbitals e.g. CaO, MgO, etc. are Lewis bases. Examples are. H +, Cu +, Zn +, Mg 2+, Li +, etc. Examples. Sulfur trioxide undergoes many reactions. SO3 is the anhydride of H2SO4. Thus, it is susceptible to hydration: SO3 + H2O → H2SO4 (ΔHf = −200 kJ/mol) Gaseous sulfur trioxide fumes profusely even in a relatively dry atmosphere owing to formation of a sulfuric acid mist. SO3 is aggressively hygroscopic. The heat of hydration is sufficient that mixt…
