Now that the metal has been isolated, scientists determined that this unknown metal could be either Lead (Pb) or Aluminum (AI). Below is a list of properties that could be used to identify the unknown metal extracted from the water. Choose the best intrinsic property that would determine if the metal is Lead (Pb) or Aluminum (AI).

List four observations that indicate that a chemical reaction may be taking place

Earth's axis of rotation is tilted at an angle of 23.5 degrees. what is one change you would see on earth if its axis was not tilted?
