Identify each substance or object below as part of the system or the surroundings. Explain.
Column A
1.Shredded aluminum (Al) foil
2.Iodine (I2) pellets
3.The air in the chemistry lab.
4.The marble counter top
5.Aluminum iodide (AlI3)
6.The metal bowl
Column B
a.Surroundings
b.System
Column A:
1. Shredded aluminum (Al) foil - System: The shredded aluminum foil is part of the system because it is an active participant in the chemical reactions or processes taking place in the system.
2. Iodine (I2) pellets - System: The iodine pellets are part of the system because they are being reacted with other substances or undergoing physical changes within the system.
3. The air in the chemistry lab - Surroundings: The air in the chemistry lab is not directly involved in the chemical reactions or processes of the system. It is considered part of the surrounding environment.
4. The marble counter top - Surroundings: The marble counter top is not directly involved in the chemical reactions or processes of the system. It is considered part of the surrounding environment.
5. Aluminum iodide (AlI3) - System: Aluminum iodide is part of the system because it is a product or result of the chemical reactions or processes taking place in the system.
6. The metal bowl - System: The metal bowl is part of the system because it is an active participant in the chemical reactions or processes occurring in the system.
Column B:
a. Surroundings: The air in the chemistry lab and the marble counter top are considered part of the surroundings because they are not directly involved in the chemical reactions or processes of the system.
b. System: The shredded aluminum foil, iodine pellets, aluminum iodide, and metal bowl are part of the system because they are directly involved in the chemical reactions or processes occurring within it.
