A student investigates the properties of an unknown liquid substance in a beaker. The student finds the substance has a mass of 56.2 g and a volume of 42.3 mL. The liquid has a yellow, cloudy appearance. The liquid has a freezing point of 13°C and a boiling point of 105°C. When the liquid boils, a white powder residue is left in the beaker.
What conclusion can the student make based on the evidence collected?
The substance is a pure substance because it has a density that remains constant.
The substance is a mixture because it has a yellow and cloudy appearance.
The substance is a pure substance because it has a definite freezing point and boiling point.
The substance is a mixture because it left a white powder in the beaker when boiled.
