what are the properties chemical reaction?

Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.

physical property: Any characteristic that can be determined without changing the substance's chemical identity. chemical property: Any characteristic that can be determined only by changing a substance's molecular structure.

Reactivity is surely a chemical property as it is determined by the valence electrons of a substance. Secondly, always a chemical change determines physical change in the substance. So if chemical properties of a substance is changed then surely its physical properties will have some or the other change.

These properties are classified as physical properties and chemical properties. Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness.

Chemical reactions help us understand the properties of matter. By studying the way a sample interacts with other matter, we can learn its chemical properties. These properties can be used to identify an unknown specimen or to predict how different types of matter might react with each other.

Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.

A chemical property is a characteristic that can only be seen when the material changes and a new material is formed. Examples of chemical properties are ability to burn, ability to rust and ability to sour. So a chemical property of wood is its ability to burn. When it burns, it gets hot and changes to ash.

The chemical properties of an element are due to the distribution of electrons around the atom's nucleus, particularly the outer, or valence, electrons; it is these electrons that are involved in chemical reactions.

The important chemical properties of organic compounds are Combustion: Carbon in all its allotropic forms burns in air or oxygen to give carbon dioxide and releases energy in the form of heat and light. Most carbon compound also release a large amount of heat and light on burning.
