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.
What is a chemical property hardness ability to react with oxygen color or freezing point?
Hardness is a physical property that describes the ability of a substance to resist deformation. Ability to react with oxygen is a chemical property that describes how a substance interacts with oxygen. Color is a physical property that describes the visual appearance of a substance. Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid.
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.
What is an example of chemical property density flammability hardness luster?
An example of a substance with high density is lead, which is dense and heavy. Gasoline is an example of a substance with flammability, as it can easily catch fire. Diamond is an example of a substance with hardness, as it is one of the hardest known natural materials. Silver is an example of a substance with luster, as it has a shiny and reflective appearance.
What is the identity of a substance?
The identity of a substance refers to its unique characteristics that distinguish it from other substances. This includes its chemical composition, physical properties, and behavior under various conditions. Identifying a substance involves analyzing these properties to determine what it is.
A characteristic of a substance that does not involve a chemical chance such as density color or hardness?
Physical Change
What five special properties make a substance a mineral?
To be classified as a mineral, a substance must have a naturally occurring, inorganic solid structure with a specific chemical composition and crystal structure. Additionally, minerals have characteristic physical properties such as hardness, cleavage, luster, and color.
A characteristc of a substance that does not involve a chemical change such as density color or hardness?
physical property
What substance is equal in hardness to a diamond?
No natural substance is equal in hardness to a diamond.
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.
What is a chemical property hardness ability to react with oxygen color or freezing point?
Hardness is a physical property that describes the ability of a substance to resist deformation. Ability to react with oxygen is a chemical property that describes how a substance interacts with oxygen. Color is a physical property that describes the visual appearance of a substance. Freezing point is a physical property that indicates the temperature at which a substance changes from a liquid to a solid.
A substance with a hardness of 8 will scratch a substance with a hardness of 7?
Yes, a substance with a hardness of 8 on the Mohs scale will scratch a substance with a hardness of 7. The Mohs scale compares the hardness of minerals, and a substance can scratch any mineral with a lower number on the scale.
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.
Which of the following in not a main characteristic of a mineral?
The ability to produce energy is not a main characteristic of a mineral. Minerals are typically characterized by their chemical composition, crystal structure, hardness, and color.
What is the hardness of chrome diopside?
Chlorine, like any other chemical substance, has no hardness unless it is in its solid state. Even then, a temperature would have to be specified for a meaningful answer.
Why does hardness not a property of substance?
Hardness is a property of substances.
Is color and hardness examples of chemical properties?
This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
