Praxis 5511 Practice Question
Which of the following describes a chemical property of substrate X?
Correct Answer: C
Rationale: Chemical properties describe how a substance interacts with other substances, resulting in a change in composition. Option C highlights that substrate X reacts with nitric acid, producing a noxious brown gas, indicating a chemical change.
Option A refers to electrical conductivity, a physical property, as it does not involve a change in the substance's chemical structure. Option B mentions the melting point, which is also a physical property, indicating a change in state rather than composition. Option D describes evaporation, a physical change where the substance remains chemically the same. Thus, only option C accurately reflects a chemical property of substrate X.
