How can a researcher test if heating sulfur forms a new substance?
Understand the Problem
The question is asking how a researcher can determine if heating sulfur changes it into a new substance. It presents multiple-choice options related to physical and chemical changes.
Answer
If the solid has a boiling point greater than 4,442.72°C, a new substance has formed.
The final answer is if the solid has a boiling point greater than 4,442.72°C, a new substance has formed.
Answer for screen readers
The final answer is if the solid has a boiling point greater than 4,442.72°C, a new substance has formed.
More Information
Changing the boiling point compared to the original sulfur properties would indicate a new substance is formed due to chemical change like forming sulfides.
Tips
A common mistake is to confuse physical state changes with chemical changes. Ensure to relate to property changes, not just physical transformations.
