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.

You are still fascinated by the process of inkjet printing, as described in the opening storyline for this chapter. you convince your father to take you to his manufacturing facility to see the machines that print expiration dates on eggs. you strike up a conversation with the technician operating the machine. he tells you that the ink drops are created using a piezoelectric crystal, acoustic waves, and the plateau-rayleigh instability, which creates uniform drops of mass m = 1.25 ✕ 10−8 g. while you don't understand the fancy words, you do recognize mass! the technician also tells you that the drops are charged to a controllable value of q and then projected vertically downward between parallel deflecting plates at a constant terminal speed of 20.0 m/s. the plates are ℓ = 2.15 cm long and have a uniform electric field of magnitude e = 6.40 ✕ 104 n/c between them. noting your interest in the process, the technician asks you, "if the position on the egg at which the drop is to be deposited requires that its deflection at the bottom end of the plates be 0.17 mm, what is the required charge on the drop (in c)? " you quickly get to work to find the answer. (neglect the force of gravity.)
