Chemical change. Bonds are being broken.
This is a chemical change (thermal decomposition).
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
Sodium chloride is a compound because it is formed by a chemical bond between sodium and chlorine atoms. In a compound, the elements are chemically bonded in fixed proportions, creating a new substance with different properties than its components. A mixture, on the other hand, is a physical combination of substances that can be separated by physical means. Sodium chloride cannot be separated back into its original elements by physical means.
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.
Heating is a physical process but thermal decomposition is a chemical process.
It is a chemical change, where a chemical such as oxygen or chlorine combines with a metal, forming an oxide or chloride of that metal.
Chemical
This is a chemical change (thermal decomposition).
It is a chemical change.2NaCl --> 2Na + Cl2
Sodium chloride is a chemical compound (NaCl), not a property.
The decomposition is a chemical process.
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.
When hydrogen burns in chlorine gas, it undergoes a chemical change. This is because new substances are formed as a result of the reaction, such as hydrogen chloride. The properties of the starting materials are different from those of the products.
Neither, Sodium Chloride (NaCl) is a salt (table salt) made by reacting the metal Sodium with the Gas Chlorine. The substance, Sodium Chloride, has both physical and chemical properties but is not a property itself.
