Praxis 5005 Practice Question
Which of the following is true of sodium chloride?
Correct Answer: B
Rationale: Sodium chloride, commonly known as table salt, consists of sodium (Na) and chlorine (Cl), making it a compound formed from two different elements, thus validating option B.
Option A is incorrect; sodium chloride is a solid at room temperature, not a gas. Option C misinterprets the nature of sodium chloride; it is a single compound, not made from two different compounds. Lastly, option D is misleading as sodium chloride is chemically stable under normal conditions, maintaining its structure without decomposing. Understanding these distinctions clarifies the properties of sodium chloride effectively.
