Interpretation: The property that cannot be used to distinguish table sugar and table salt should be identified.
Concept Introduction: A change that affects the form of a substance but not its chemical composition is said to be physical.
Answer to Problem 4STP
Correct answer: Color.
Explanation of Solution
Reason for correct option: The color of table salt and table sugar is the same that is white so it is not possible to distinguish between table salt and table sugar based on color.
Reasons for incorrect options:
Boiling point, melting point, and density: The boiling point, melting point, and density of table salt and table sugar are completely different from one another. The difference in the values of these terms between table salt and table sugar is quite large and can be used to distinguish table sugar and table salt.

- Draw and show the full mechanism of how the molecule ((1E, 3E, 5E)-1-methoxyhepta-1,3,5-triene) is built using substitution and elimination reactions. You can start with an alkane of any carbon length with any number of leaving groups attached or with a alkoxide of any carbon length (conjugate base of an alcohol). Show each step and and explanation for each reaction. Also include why the reagents and solvents were picked and what other products can be expected.arrow_forwardDon't USE AIarrow_forwardDon't USE AIarrow_forward
