A somatogenic change happens when the substance changes in appearance except maintains its corporal and chemical properties. A chemical change occurs when a different substance forms with newly make physical and chemical properties. The scratch substance was milligram. sooner it was heated, it was a shiny specie strip. It was smooth, malleable, and flat. When heated, a bright light was emitted. The new substance magnesium oxide was white, chalky, brittle, and dull. The light given off and the new substance formed both indicate a chemical change. The second substance was copper. Before we heated it, it was shiny, round, smooth, and a copper affecta tion. After it was heated, the color chang! ed to blue. It was no longer shiny, but dull. The copper turned red when fixed in the flame, due to the heat. Due to the change in color, we...If you emergency to get a full essay, order it on our website: OrderEssay.net
