In chemistry, the system is the reaction that you are studying, including the reactants and the products. The surroundings are everything outside the system, including the container the reaction is taking place in. Look at the picture of the double replacement reaction below of silver nitrate and sodium chromate that produces silver chromate and sodium nitrate. The balanced equation is also shown. Identify each of the parts below as part of the system or part of the surroundings. Column A 1. Silver Nitrate - AgNO3 : Silver Nitrate - AgNO3 2. Gray lab table: Gray lab table 3. Sodium Chromate - Na2CrO4 : Sodium Chromate - Na2CrO4 4. Air in the room: Air in the room 5. The glass flask (container) the reaction is taking place in. : The glass flask (container) the reaction is taking place in. 6. Silver Chromate - Ag2CrO4 : Silver Chromate - Ag2CrO4 7.
