7 ve- and in the Halogens.
True or False: Toast is not a chemical change because the sucralose just changes color.
False.
A lump of Dry Ice has sublimated, which is a Physical change. How does sublimation occur?
"Sublimation occurs when the surface particles of a solid gain enough energy that they form a gas" (Savvas Science Book pg 453)
