The metal burns in air to form zinc (II) oxide, a material that goes from white to yellow on prolonged heating. Q:Disulfur dichloride, S2Cl2 is used to vulcanize rubber. Recall that oxides of metals are basic and oxides or nonmetals are acidic; this is true for all elements in Group 13, except Al and Ga. All other Group 13 elements also produce compounds of the form of M2O3, but adhere to the acid-base rules of metal and nonmetal oxides. The decomposition of potassium chlorate, KClO3, into KCl and O2, is used as a source of oxygen in the laboratory. Disulfur dichloride, S2Cl2, is used to vulcanize rubber. B.
