this is a chemical change.
Reacting violently with chlorine is a chemical property because it describes how a substance undergoes a chemical change when coming in contact with another substance, in this case, chlorine.
Chlorine is doing it chemically. It reacts with it.
No, the release of energy when sodium metal reacts with chlorine gas is a chemical property, not a physical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties are characteristics that can be observed without changing the substance's composition.
Chlorine is reactive and can form compounds with many other elements. It commonly reacts with metals to form metal chlorides, and with nonmetals to form covalent compounds. Its reactivity makes it an important component in a variety of chemical processes and products.
Sulfur reacts with chlorine to form sulfur dichloride, which has the chemical formula SCl2.
A chemical difference is that sodium reacts with water to make an alkali, and chlorine plus water give acids. A physical difference is that sodium is a solid at room temperature and chlorine is a gas.
When something reacts, that is a chemical reaction. Chemical change.
Gallium chloride has the chemical formula GaCl3.
Physical: In pure form it is a shiny metal. It has a low density. It is malleable. Chemical: In pure form it corrodes easily upon exposure to air. It reacts violently with water to form potassium hydroxide and release hydrogen gas.
chemical...main word reacts!
The property exhibited when a substance reacts violently with sodium is known as reactivity. This usually indicates that the substance is highly reactive and can form a strong chemical reaction with other elements or compounds.
The formation of NaCl (sodium chloride) from sodium and chlorine is a chemical change because it involves a reaction that results in the creation of a new substance with distinct properties. When sodium reacts with chlorine gas, they undergo a chemical reaction that produces NaCl, which cannot be reversed by simple physical means. In contrast, physical changes involve alterations in form or state without changing the chemical identity of the substance.
