What else can I help you with?
Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 at 25 is it physical or chemical change?
The hardness and density of zinc are physical properties, as they do not involve any change in the chemical composition of the substance. Changes in physical properties can be observed without altering the chemical identity of the material.
Is hardness physical change or chemical change?
Hardness is a physical change. It does not involve a change in the chemical composition or structure of a substance, but rather a change in its physical properties such as strength or resistance to deformation.
Are the melting point and hardness physical properties?
Hardness and melting point are physical properties.
Melting point hardness and density are all examples of (physicalchemical) properties.?
Melting point, hardness, and density are all examples of physical properties. These properties describe the characteristics of a substance without altering its chemical composition. Physical properties can be observed or measured without changing the identity of the material. In contrast, chemical properties involve the substance's ability to undergo chemical changes or reactions.
What are some physical and chemical properties of elements?
Physical properties: density, melting point, boiling point, hardness, refractive index, resistivity etc.Chemical properties: chemical reactivity, electronegativity, flammability, corrosivity, heat of combustion etc.
How can minerals be identifed by their physical properties?
Yes
What are the physical and chemical properties?
Some physical properties are: density, color, refractive index, hardness, thermal conductivity, electrical conductivity, melting point, boiling point etc. Some chemical properties are: reactivity, corrosiveness, inflammability etc.
Does a chemical property or physical property scratch glass?
A physical property, such as hardness, is what allows a material to scratch glass. Materials with a hardness greater than glass (5.5 on the Mohs scale) can scratch it. Chemical properties do not directly influence the scratching of glass.
Is it able to conduct a physical or chemical?
Hardness a physical or chemical
What are physical properties of matter?
The physical properties of matter is something that can be observed or measured without changing the chemical properties. ex: color, odor, boiling point, melting point, density, hardness, etc.
What the physical and chemical properties of matter?
Physical properties: mass, density, hardness, electrical conductivity, melting point, boiling point etc.Chemical properties: reactivity, flammability, heat of combustion, corrosivity etc.
Are properties of matter physical?
The physical properties of matter is something that can be observed or measured without changing the chemical properties. ex: color, odor, boiling point, melting point, density, hardness, etc.
