Final answer:
Its a a) Claim that when a chemical reaction occur when water is heated on a stove.
Step-by-step explanation:
In the scientific method, a claim is a statement that answers the research question. In this case, the claim is whether a chemical reaction occurs when water is heated on a stove. It serves as the overarching conclusion or assertion based on evidence and reasoning.
When water is heated on a stove, a chemical reaction does not occur; instead, a physical change takes place. The heat energy is absorbed by the water molecules, causing them to gain kinetic energy and transition from a liquid to a gaseous state (steam). This phase change is a physical process, not a chemical reaction. The chemical composition of water remains H₂O throughout the process.
The evidence supporting this claim comes from the understanding of the physical properties and behavior of water under different temperature conditions. The scientific explanation involves knowledge of the water cycle, phase changes, and the distinction between physical and chemical changes. By applying these science ideas, one can confidently claim that heating water on a stove leads to a physical change, not a chemical reaction.
In summary, the question "Is I₄⁻ consistent?" is equivalent to assessing whether the I₄⁻ ion conforms to the octet rule, ensuring a stable electronic arrangement for each iodine atom in the structure.
