Do a chemical and physical property both describe characteristics of a substance?
yes they do!
Is blue color a chemical property or physical property?
Blue color is a physical property. It is a physical property because being blue does not change the chemical composition.
What are the definitions of chemical and physical properties?
Chemical properties describe how a substance interacts with other substances to form new chemical bonds or undergo chemical reactions. Physical properties, on the other hand, describe the characteristics of a substance that can be observed without changing its chemical identity, such as color, density, and melting point.
Can you consider hemoglobin molecules have a red color as a chemical property?
Hemoglobin molecules having a red color is not considered a chemical property, but a physical property. Chemical properties involve the way a substance interacts with other substances in chemical reactions, while physical properties relate to observable characteristics like color, density, and melting point.
Is chemical formula H2O physical or chemical property?
The chemical formula H2O itself is a chemical property because it represents the specific composition of water molecules. Physical properties, on the other hand, describe characteristics that can be observed or measured without changing the substance's chemical identity.
