Why is melting wax a physical properties of flammability is a chemical property?
Melting is a physical property because the chemical composition remain unchanged.Flammability is a chemical property because involve a combustion reaction.
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 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.
Is yttruim physical or chemical properties?
Yttrium possesses both physical and chemical properties. Its physical properties include being a silvery metal with a high melting point, while its chemical properties include reacting with oxygen to form yttrium oxide and with acids to form salts.
How to identify substances using their properties?
Substances can be identified by their physical and chemical properties. Physical properties include characteristics like color, density, melting point, and boiling point. Chemical properties involve reactivity, such as how a substance reacts with other substances or undergoes chemical changes. By comparing these properties with known data in a reference guide or database, you can help identify the substance.
Is shortening melting a chemical property?
No, shortening melting is a physical property. Chemical properties involve changes in the chemical makeup of a substance, while physical properties describe characteristics that can be observed without changing the substance's chemical composition.
What are physical and chemical properties of salt?
it has an high melting point
Why is melting wax a physical properties of flammability is a chemical property?
Melting is a physical property because the chemical composition remain unchanged.Flammability is a chemical property because involve a combustion reaction.
What do The physical properties of compounds not include?
The physical properties of compounds do not include chemical reactivity, which relates to how a substance undergoes chemical changes. Physical properties pertain only to characteristics such as color, melting point, boiling point, density, and solubility.
Why is melting a physical?
Because melting only affects the state of matter that the melted substance is, it doesn't change the chemical properties.
What is melting physical proreties of wax but frammabillty is a change propeties?
Melting is a physical property because it only changes the physical state of the substance, such as wax, but does not change its physical or chemical properties. This is because melting is not a chemical reaction. Flammability, however, is a chemical property, and when a substance burns, that is a chemical reaction, and the physical and chemical properties of the products will be different than the reactants (starting substances).
Whay is melting physical proreties of wax but frammabillty is a change propeties?
Melting is a physical property because it only changes the physical state of the substance, such as wax, but does not change its physical or chemical properties. This is because melting is not a chemical reaction. Flammability, however, is a chemical property, and when a substance burns, that is a chemical reaction, and the physical and chemical properties of the products will be different than the reactants (starting substances).
Is mealting a chemical reaction?
No, melting is a physical change of state, the chemical properties and formula of the substance remain unchanged.
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.
Is melting ice example of chemical property?
No, melting ice is a physical change because it does not involve a change in the chemical composition of the substance. Chemical properties describe how a substance reacts with other substances to form new substances.
How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
Boiling point melting and density are some of an elements nonreactive physicalor chemical properties?
Boiling point, melting point, and density are all physical properties of an element. They determine the state of the element.
