Sugar with water? Proceed with caution. Almost all of the metals, transition metals, and metalloids are lustrous. Since a chemical change did not occur, choice A is not the correct answer. A change in color is also another characteristic of a chemical reaction taking place. Water has a lower viscosity than honey or magma, which have relatively high viscosities. When a compound, which consists of two or more elements or groups of elements, is broken down into its constituents, the reaction is called simple decomposition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

The ions display different properties from the original compound. is noticed, a chemical reaction is probably occurring. This is one of the gray areas of chemical change and physical change. This means that the metals can deform under an amount of stress. 2. 2. That's a really strange question; sounds like a trick question. When, for example, water is decomposed, its molecules, each of which consists of one atom of oxygen and two of hydrogen, are broken down; the hydrogen atoms then combine in pairs to form hydrogen molecules and the oxygen atoms to form oxygen molecules. Basics of the Reaction The acetic acid in the vinegar literally dissolves the egg’s shell. If you can see them separate, it's probably not a chemical change. its physical and chemical properties. As ice turns into water, it does not retain a solid shape and now becomes a viscous fluid.
