Is heating of ammonium chloride in a test tube a physical or chemical change?
This is a chemical change (thermal decomposition).
When hydrogen burns in chlorine gas it is a physical or chemical change?
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.
Why is sodium chloride a compound and not a mixture of sodium and chlorine?
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.
Is reacts violently with chlorine physical or chemical property?
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.
Is heating ammonium bicarbonate a physical or chemical change?
Heating is a physical process but thermal decomposition is a chemical process.
Is corrosion of metals physical or chemical change?
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.
Is Potassium chloride decomposes to potassium chloride and oxygen gas is a physical or chemical change?
Chemical
Is heating of ammonium chloride in a test tube a physical or chemical change?
This is a chemical change (thermal decomposition).
When chlorine gas is separated from sodium chloride gas which change will occur physical or chemical?
It is a chemical change.2NaCl --> 2Na + Cl2
Is sodium chloride a chemical or physical property?
Sodium chloride is a chemical compound (NaCl), not a property.
Sodium metal in chlorine gas releases energy is it a physical property?
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.
Is decomposition of water into its elements a physical process?
The decomposition is a chemical process.
When hydrogen burns in chlorine gas it is a physical or chemical change?
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.
Is sodium cloride a physical property or a chemical property?
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.
Is NaCI a physical or chemical change?
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.
Is reacts violently with chlorine physical or chemical?
this is a chemical change.
Is sodium and chlorine a physical change or a chemical change?
