Almost all of the metals, transition metals, and metalloids are lustrous. Examples of physical changes could be boiling, melting, freezing, and shredding. Thus, we shall simply refer to physical "reactions" as physical changes from now on. It is just carbon dioxide being released. The solid table salt is added to the water and disappears. Example. And there isnt really much gas in the candy and soda pop combinedonly enough to inflate the balloon a little bit. Explanation: When substances are put in the same container like, CaCO3 and H Cl. In a chemical change, 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 soda pop company puts the carbon dioxide in the soda to give it that special fizz. This is because of chemical reactions that take place as the food begins to break down and go bad, which leads to the formation of new substances that have unique smells associated with them.Another common sign of a chemical reaction is the formation of a precipitate. The carbon dioxide gas can originally be seen as bubbles in the solution, but will quickly be released from the solution. In other words, this is a physical reaction, not a chemical reaction.
