Question

Jesse was viewing two water samples. Once beaker was filled with 250 mL of distilled water and the other beaker was filled with 250 mL of tap water. Upon viewing the two using an electron microscope, he noted that the tap water had different elements present in addition to H2O molecules, whereas the distilled water had only H2O molecules. Which conclusion below could Jesse write based on his observations? Question 12 options: Tap water is a mixture, as it is made of different particles that keep their own chemical properties. Distilled water is a mixture made up of hydrogen and oxygen atoms. Tap water is a mixture that consists of different molecules that are not bonded together and maintain their own chemical properties. Distilled water is a pure substance that is made up of one type of molecule, making it an element. Tap water is a pure substance that consists of different elements bonded together, therefore it is a compound. Distilled water is also a pure substance with different elements bonded together, making it a compound. Tap water is a mixture that consists of different molecules that are not bonded together and maintain their own chemical properties. Distilled water is a pure substance that consists of only one type of compound.
