Question 1

A gold wire has a diameter of 1.00 mm.  What length of this wire contains exactly 1.00 mol of gold? (density of Au = 17.0 g/cm3)
◦ 2630 m
◦ 3.69 m
◦ 251 m
◦ 14.8 m
◦ 62.7 m

Question 2

A mass spectrometer works by ionizing atoms or molecules, and then accelerating them through oppositely charged plates. The mass is obtained by
◦ measuring the force of impact on a detecting screen, and then calculating the mass using force = mass × acceleration.
◦ suspending the ions in an applied electric field, and then calculating mass by the setting the downward gravitational force equal to the upward electrostatic force.
◦ measuring the magnitude of deflection as the ions pass through a magnetic field to obtain the charge-to-mass ratio, and then calculating the mass from that ratio.
◦ measuring the time it takes for the ions to hit the detector at a known distance to calculate the acceleration, and then calculating mass from force = mass × acceleration.

Stevens-Johnson syndrome and Toxic Epidermal Necrolysis syndrome are life-threatening reactions that can result in death. Complications include permanent blindness, dry-eye syndrome, lung damage, photophobia, asthma, chronic obstructive pulmonary disease, permanent loss of nail beds, scarring of mucous membranes, arthritis, and chronic fatigue syndrome. Many patients' pores scar shut, causing them to retain heat.
