The paints and varnishes that used on fishing boats can be degraded by solar radiation through photochemical reactions. Hence, the boats must be protected from the effects of solar radiation by incorporating UV protection additives, such as UV additive Z into the paints and varnishes. Given that: M = 500 g-moL Emax = 15500 L'mol cm for Amax = 380 nm, calculate the concentration of UV additive Z such that 90% of the radiation is absorbed by a coating thickness of 0.3 mm. Express the answer in g-L with 2 decimal places. 1.

Electrochemical Equilibria: Electrolytic DepositionOlympic gold medals are plated with gold rather than being pure gold. A minimum of 6 grams of gold (MW = 196.97 g/mol) and at least one gram of silver (MW = 196.97 g/mol) must be present in an Olympic gold medal.Silver content is 92.5 percent. A total of 340 gold medals were awarded at the Tokyo Olympics in 2021 to athletes who are deserving Assume each medal is made by coating a 60-mm diameter, 3-mm thick, gold-free silver disc with a gold-free coating. Determine the alloying of a disk with gold via electrolytic deposition using a gold (III) solution. following: a) Time in hours required to finish plating all gold medals used in the Tokyo Olympics If the available electricity source can deliver 50 current in amperes, the Olympics will have a minimum gold content.

A Water Quality Standard will be developed for radioactive isotope “Iron-55” which has physical (radioactive) and biological half-lives of 2.7 and 1.6 years, respectively. Through toxicological studies scientists decided “spleen” as the critical organ and the critical accumulation of Iron-55 in spleen has been determined to be 0.5 gram. Assuming radioactive exposure is only due to drinking water consumption and average life expectancy is 75 years. a) What should be the Maximum Concentration Level (MCL) as mg/L for Iron-55 in drinking water. b) How long does it take to eliminate 95% of this radioactive isotope from human spleen after the person gives up on drinking water contaminated with Iron-55?
