What else can I help you with?
Describe chemical and physical properties and give examples of each?
A physical property is one that can be changed without altering the chemical formula of the substance, e.g., gas to liquid. A chemical property is one that is unique to that substance and altering it will change that substance chemically, e.g. density or molar mass.
Is density an example of a chemical change?
No, density is simply a property of a substance. It's how "heavy" something is. Water, for example, has a density of 1 gram per milliliter. Meaning every milliliter weighs one gram. Some are much more (Mercury), some are much less (Air).
Can one physical property of paper is that it will burn easily?
That is a chemical property. A physical property could be its mass, volume, density, physical state, or that it can tear easily. A physical property is one that does not change the chemical composition of the substance.
What is the property that is a quality of a substance that never changes and can be used to indentify the substance?
A quality of a substance that never changes is one of the reasons why density is a characteristic property
Which measurable property cannot be used to tell one chemical substance from another?
One measurable property that cannot reliably distinguish one chemical substance from another is density, as many substances can have similar or even identical densities. Additionally, density can change with temperature and pressure, further complicating its use as a distinguishing factor. Other properties, such as boiling point, melting point, and solubility, are often more definitive for identifying specific substances.

How is a chemical property different from a physical property?
A chemical property describes how a substance reacts or changes to form a new substance, such as flammability or reactivity. A physical property, on the other hand, describes characteristics of a substance that can be observed or measured without changing its identity, such as color, density, or melting point.
Is density a property of an object or a property of the substance the object or a property of the substance the object is made of?
Density is a property of a substance, not an object. It is the mass of a substance per unit volume. The density of a substance remains the same regardless of the size or shape of the object made from it.
Is density an example of a chemical change?
No, density is simply a property of a substance. It's how "heavy" something is. Water, for example, has a density of 1 gram per milliliter. Meaning every milliliter weighs one gram. Some are much more (Mercury), some are much less (Air).
A physical property is a characteristic of a substance is one that?
Density is a physical property; physical properties are measurable.
Is reacts with acid physical property or chemical property?
it is chemical change

That is a chemical property. A physical property could be its mass, volume, density, physical state, or that it can tear easily. A physical property is one that does not change the chemical composition of the substance.
Is density a physical or chemical change or is it a physical and chemical change?
Your answer will be physical property.It can also be physical change when you're telling the density of an object. And the reason why is "density" is... physical is just those kind of stuff...
What is the property that is a quality of a substance that never changes and can be used to indentify the substance?
A quality of a substance that never changes is one of the reasons why density is a characteristic property
Is density a consistent physical property for any one particular substance?
Density is a physical property. It is also time-consistent, but not temperature-consistent.
What property is one that involves the production of a new substance?
A chemical property involves the production of a new substance. This occurs when a substance undergoes a chemical reaction that results in the formation of one or more different substances with different chemical compositions.
Which measurable property cannot be used to tell one chemical substance from another?
One measurable property that cannot reliably distinguish one chemical substance from another is density, as many substances can have similar or even identical densities. Additionally, density can change with temperature and pressure, further complicating its use as a distinguishing factor. Other properties, such as boiling point, melting point, and solubility, are often more definitive for identifying specific substances.
