... PSQ-6: Mercury (II) oxide is a battery used in watches. As electric current flows, it is being reduced to liquid mercury. If 2.01 amperes flow continuously in the system, how many grams of mercury is produced every half hour? Hgo(s) + H2O() + 2e - Hg() + 20H-(aq) (MW Hg = 200 g/mol; Faraday's constant = 96480 C/mol e) Round off your final answer two decimal places. Do not write the unit.
At high altitudes, mountain climbers are unable to absorb a sufficient amount of O2 into their bloodstreams to maintain a high activity level. At a pressure of 1.00 bar, blood is typically 95.0% saturated with O2, but near 0 feet where the pressure is 0.660 bar, the corresponding degree of saturation is 60.0%. Air contains 20.99% O2 by volume. Assume that the density of blood is 998 kg m -3 Part A Assuming that the Henry's law constant for blood is the same as for water (4.95 x 104 bar), calculate the amount of O₂ dissolved in 1.00 L of blood for pressure of 1.00 bar.
