Solution Steps

Step 1: Understand the Given Information

The problem states that table salt, which is a compound, can be separated into sodium and chlorine. It provides additional information about the properties of these elements: sodium is explosive, and chlorine is a toxic gas.

Step 2: Analyze the Statements

The statements imply that while table salt is generally considered safe, its constituent elements, sodium and chlorine, are individually hazardous. This suggests that the separation of a compound into its elements can change its properties significantly.

Step 3: Evaluate the Multiple-Choice Options
  • Option A: A harmful compound can become harmless when its elements are separated. This is incorrect because table salt is not harmful in its compound form.
  • Option B: A harmless compound can become harmful when its elements are separated. This is correct because table salt is harmless, but its elements, sodium and chlorine, are harmful.
  • Option C: Breaking a compound into its separate elements has no noticeable effect. This is incorrect because the elements have very different properties from the compound.
  • Option D: Breaking a compound into its separate elements can create carbon dioxide. This is incorrect because carbon dioxide is not related to the separation of sodium and chlorine.

Final Answer

The correct conclusion from the statements is that a harmless compound can become harmful when its elements are separated. Therefore, the answer is:

\[ \boxed{\text{B}} \]

Consider a diagram in which the variable measured on the y-axis remains constant while the variable measured on the x-axis increases. The graph of these two variables is a horizontal line, a vertical line, a line that has a negative slope, non-existent because the two variables are not related, or a line that has positive slope.
