Oxidation is a chemical reaction; but a physical modification can also occur.
When oxidation occurs, it typically involves a chemical change. This process involves the transfer of electrons, leading to the alteration of the chemical composition of the substance being oxidized. While some physical changes may accompany oxidation (such as color changes), the core of oxidation itself is a chemical transformation.
chemical property.
A chemical property of a substance refers to its ability to undergo a chemical change or reaction to form new substances. This property is related to the substance's composition and arrangement of atoms. Examples of chemical properties include reactivity with other substances, flammability, and acidity or basicity.
"Very reactive" is a chemical property because it describes how likely a substance is to undergo a chemical reaction with other substances. It does not pertain to any physical characteristic of the substance.
Reactivity is a chemical property, not a physical change. It refers to the ability of a substance to undergo a chemical reaction with another substance. Physical changes involve alterations in the form or state of a substance without changing its chemical composition.
Dissolving in water is a physical change because the chemical composition of the substance remains the same. The particles of the substance are dispersed in the water but do not undergo a chemical reaction to form new substances.
Copper sulfate dissolving in water is a physical change as no new substance is formed. However, if copper sulfate is heated to decomposition, it would be a chemical change because a new substance is formed.
Element oxidation state is a chemical property, as it is related to the number of electrons an atom gains, loses, or shares when forming chemical bonds with other atoms. It reflects an element's ability to undergo chemical reactions.
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.
Density is a physical property of a substance, not a chemical property.Density is a measure of how much mass is contained in a given volume of a substance. Chemical properties describe how a substance interacts with other substances, such as its reactivity or ability to undergo chemical changes.
