Question

In the process of attempting to ch aracterize a substance, a chemist makes the fo llowing observations: The substance is a silvery white, lustrous metal. It melts at 649∘C and boils at 1105∘C.Its density at 20∘C is 1.738g/cm3.The substance burns in air, producing an intense white light. It reacts with chlorine to give a brittle white solid. The substance can be pounded into thin sheets or drawn into wires. It is a good conductor of electricity. Which of these characteri stics are physical properti es, and which are chemical properties?

Answer 1

Answer:

Here's what I get  

Explanation:

A physical property is one you can observe without changing the chemical composition of a substance.

A chemical property is one you can observe only by changing the chemical composition of a substance.

In this problem, examples of physical properties are:

• Colour
• Lustre
• Melting point
• Boiling point
• Density
• Malleability
• Ductility
• Conduction of electricity

Examples of chemical properties are:

• Burning in air
• Reaction with chlorine
