What else can I help you with?
Is gas considered a chemical substance?
Yes, gas is considered a chemical substance because it is composed of molecules or atoms that have specific chemical properties. Gases can undergo chemical reactions with other substances, and their behavior can be described using principles of chemistry.
Can only be determined by changing a substance?
Chemical properties can only be determined by changing a substance.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
Why is naphthalene a pure substance?
Naphthalene is considered a pure substance because it is a chemical compound made up of only naphthalene molecules. It has a definite and consistent chemical composition, with uniform properties throughout its structure.
Do chemical changes affect the chemical structure of a substance?
Yes, chemical changes result in a change in the chemical structure of a substance. During a chemical change, new substances with different chemical compositions are formed through the rearrangement of atoms and bonds. This is in contrast to physical changes, where the chemical structure remains the same even though the physical properties may change.
What is the relationship between the chemical properties of a substance and the chemical change of substance?
The chemical properties of an object show what a chemical change did to that substance.
Is the ability to react with other substances a chemical properties?
Yes, the ability to react with other substances is considered a chemical property. Chemical properties describe how a substance interacts with other substances or undergoes chemical changes. This property helps to identify the behavior of a substance in chemical reactions.

What kind of substance of water?
Water is considered a pure chemical substance. Its mass and properties are similar to many of the other constituent elements.
How are characteristic properties of given substance different from its other properties and chemical properties?
A substance's characteristic properties are the most recognizable properties of that substance. Chemical properties are exhibited as one substance is chemically transformed into another (e.g., iron rusting).
What is the diffence between physical and chemical properties as well an physical and chemical changes?
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
What are the properties of an element?

What is the relationship between the chemical property of a substance and the chemical changes of a substance?
The chemical properties of an object show what a chemical change did to that substance.

Properties that determine the chemical changes that a substance goes through are known as?
Chemical properties
What does a change in a chemical properties of a substance result in?
A chemical reaction (change) results in a change in chemical properties.
