    May 15, 2011· There is nothing "lol wtf dude seriously" about this. Simply put, metal oxides tend to behave as lewis bases while nonmetal oxides (covalent oxides) tend to be lewis acids. Compare their reaction with a single reagent, water. SO2 + H2O yields H2SO3. The lone pair on the water oxygen attacks sulfur, forming an O-S bond.

    A pyrophoric substance (from Greek πυροφόρος, pyrophoros, "fire-bearing") is a substance that ignites spontaneously in air at or below 54 °C (129 °F) (for gases) or within 5 minutes after coming into contact with air (for liquids and solids). Examples are iron sulfide and many reactive metals including plutonium and uranium, when powdered or thinly sliced.
