∙ 14y agofirstly what do u mean by phys/chem change??????
but technically it is a chemical change because there has been a reaction giving off SO2. take combustion of coal for example when burning sulfurous coal some of the sulfur compounds react with combustion medium usually being air thus being converted to SO2 in the flue gas. the reaction chemistry is unimportant but you can look anywhere on the net for that.
