Question

12c. question: are any of the liquids the same substance? directions: use the information in the data table to provide reasoning for how the evidence supports your claim. use complete sentences. reasoning:

Explanation:

To determine if any liquids are the same substance, we analyze the data table (not shown here, but typically, substances have identical physical properties like density, boiling point, freezing point, etc.). If two liquids have the same set of characteristic physical properties (e.g., same density, same solubility, same refractive index), they are likely the same substance because a substance's physical properties are inherent and unique to it (or shared only by identical substances). For example, if Liquid A and Liquid B have the same density, boiling point, and color (assuming color is a consistent property here), this evidence supports the claim that they are the same substance, as these properties are determined by the substance's molecular structure and composition.

Answer:

To determine if any liquids are the same substance, we examine their physical/chemical properties (from the data table). If two liquids have identical characteristic properties (e.g., density, boiling point, solubility), they are the same substance because a substance’s properties are inherent and unique to it. For example, if Liquid X and Liquid Y have the same density, boiling point, and reactivity (if tested), this evidence supports they are the same substance, as these properties depend on molecular composition.
