Verified step by step guidance
1
Understand the Law of Conservation of Mass, which states that mass is neither created nor destroyed in a chemical reaction. This implies that substances involved in a reaction are transformed but not lost.
Identify the substances listed: Calcium carbonate (CaCO₃), Nitrogen (N₂), Carbon dioxide (CO₂), and Oxygen (O₂).
Consider the physical states and typical behavior of these substances in the environment. Nitrogen, carbon dioxide, and oxygen are gases that naturally cycle into the atmosphere.
Recognize that calcium carbonate is a solid compound commonly found in rocks, shells, and minerals. It does not typically cycle into the atmosphere as a gas.
Conclude that calcium carbonate does not cycle into the atmosphere, unlike the other substances listed, which are gases and do participate in atmospheric cycles.
