  • How can you tell if gas is formed from a mixture?

  • gas can be formed when two liquids are combined, or when a solid is added to aliquid. Sometimes this gas has an odor and other times it doesn’t. It is generally visible asbubbles rising to the surface of the reaction mixture, but the gas can also be soluble. Ifthis is the case it is generally very difficult to see its formation in the mixture.
