A somatogenic change happens when the substance changes in appearance up to now maintains its corporal and chemical properties. A chemical change occurs when a different substance forms with newly organize physical and chemical properties. The scratch substance was magnesium. sooner it was heated, it was a shiny funds strip. It was smooth, malleable, and flat. When heated, a bright light was emitted. The new substance magnesium o! xide 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 comment.
