Which one is a chemical change electrolysis of water sodium chloride exposit to sunlight

The electrolysis of water is a chemical change. During electrolysis, water (H₂O) is broken down into hydrogen (H₂) and oxygen (O₂) gases through an electric current. This process involves breaking chemical bonds and forming new substances, which is characteristic of a chemical change. On the other hand, the exposure of sodium chloride (table salt) to sunlight would not be considered a chemical change; it primarily involves physical changes such as the evaporation of moisture if present, but the sodium chloride itself remains chemically unchanged.
