Which of the following is a chemical property?
hardness
ability to react with oxygen
color
freezing point
oop nevermind i got da answer lol its ability to react with oxygen :D
right on bro
To determine which of the following options is a chemical property, we need to understand the difference between chemical and physical properties.
A chemical property is a characteristic of a substance that describes its ability to undergo chemical reactions and form new substances. It involves the internal structure or composition of a substance and is not easily observed without physically changing the substance.
On the other hand, a physical property is a characteristic of a substance that can be observed or measured without changing the substance's identity. Physical properties include characteristics like color, hardness, boiling point, freezing point, and density.
The correct answer to your question is "ability to react with oxygen." Reactivity with oxygen is a chemical property because it describes the substance's ability to undergo a chemical reaction (oxidation) with oxygen, resulting in the formation of new compounds.
To determine whether the other options are chemical or physical properties:
- Hardness: Hardness is a physical property that refers to the resistance of a substance to being scratched or deformed.
- Color: Color is also a physical property as it refers to the visual appearance of a substance, determined by the interaction of light and the substance's molecules.
- Freezing point: Freezing point is a physical property that represents the temperature at which a substance changes from a liquid state to a solid state.
In conclusion, the only option that represents a chemical property is the "ability to react with oxygen."
