Answer 1

The student is asking to classify each statement as a physical or chemical property. a. Iron and oxygen forming rust is a chemical property. b. Iron being more dense than aluminum is a physical property. c. Magnesium burning brightly when ignited is a chemical property. d. Oil and water not mixing is a physical property. e. Mercury melting at -39C is a physical property. f. Carbon dioxide being a colorless gas is a physical property. g. Conducting electricity is a physical property.

Step-by-step explanation:

Based on the provided information, let's classify each of the following as a physical or chemical property:

1. a. Iron and oxygen form rust: This is a chemical property because it involves a chemical reaction between iron and oxygen.
2. b. Iron is more dense than aluminum: This is a physical property because it describes the relative density of iron and aluminum.
3. c. Magnesium burns brightly when ignited: This is a chemical property as it involves a chemical reaction between magnesium and oxygen that produces light and heat.
4. d. Oil and water do not mix: This is a physical property as it describes the behavior of oil and water when mixed.
5. e. Mercury melts at -39C: This is a physical property as it describes the melting point of mercury.
6. f. Carbon dioxide is a colorless gas: This is a physical property as it describes the appearance and state of carbon dioxide.
7. g. Conducts electricity: This is a physical property as it describes the ability of a substance to conduct electricity.
