Need help immediately!!
When an electric current is passed through water during the process of electrolysis, two gases are formed. One has a boiling point of -183°C and the other has a boiling point of -253°C. Has a physical change or chemical change occurs? Explain.

  • chemistry -

    hydrogen (-253ºC) and oxygen (-183ºC) were chemically combined to form water

    the electrolysis reverses that reaction

  • chemistry -

    Scott, thank you so much!!!
