Question 1

Calculate the wavelength of the light emitted by a hydrogen atom during a transition of its electron from the n = 4 to the n = 1 principal energy level.  Recall that for hydrogen En = –2.18 × 10–18 J(1/n2)
◦ 6.8 × 10–18 nm
◦ 0.612 nm
◦ 82.6 nm
◦ 97.2 nm
◦ 365 nm

Question 2

Calculate the wavelength, in nanometers, of the light emitted by a hydrogen atom when its electron falls from the n = 7 to the n = 4 principal energy level.  Recall that the energy levels of the H atom are given by
         En = –2.18 × 10–18 J(1/n2)
◦ 9.18 × 10–20 nm
◦ 4.45 × 10–20 nm
◦ 2.16 × 10–6 nm
◦ 2.16 × 103 nm
◦ 1.38 × 1014 nm

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.
