In the lab a substance is studied and the following observations are made. At room temperature (20 °C) the substance has the following properties: 1. It is a solid that is shiny and silver in color. 2. It has a density of 1.738 g/mL. 3. It is malleable (it can be pounded into a flat sheet). 4. It is ductile (it can be pulled into a thin wire). 5. It is a good electrical conductor. The substance is subjected to some further experiments and these additional observations are made. 6. It melts at 649 °C. 7. It boils at 1105 °C. 8. It burns in air, glowing with an intense white light. 9. It reacts with bromine to give a brittle white solid. Which of these characteristics are physical properties, and which are chemical properties?

Question: Chapter: 1 Lesson: 3 In the lab a substance is studied and the following observations are made. At room temperature (20 °C) the substance has the following properties: Week 1 Homework 1. It is a solid that is shiny and silver in color. 2. It has a density of 1.738 g/mL. 3. It is malleable (it can be pounded into a flat sheet). 4. It is ductile (it can be pulled into a thin wire). 5. It is a good electrical conductor. The substance is subjected to some further experiments and these additional observations are made. Hint: 6. It melts at 649 °C. 7. It boils at 1105 °C. 8. It burns in air, glowing with an intense white light. 9. It reacts with bromine to give a brittle white solid. Which of these characteristics are physical properties, and which are chemical properties? For a physical property there is no change in the identity of the substance. Chemical properties involve a change in the identity of the substances. See Pure Substances. structure.com/courses/2233243 MacBook Pro 1/3
