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 chemist received a radioactive sample that is suspected to contain U, 23U and other elements. The authority wants to know the distribution, qualitative and quantitative composition of the sample. Propose with justifications, ONE Surface analysis technique that can be performed on this sample.

Does a RAD measure accuracy or precision?

What is the process of elution in extracting Ba-137 from the Isotope Generator (2-3 sentences would do

- Give reason for 5- Isotopes have ability to undergo nuclear reactions which are very important in medical applications. 6- Radiation source in AAS device is hallow cathode lamp. 7- The PH of a solution Mg(OH)2 can affect a salt solubility by addition of H+ ion , pH decreasing while solubility of Mg(OH)2 will be increasing. * Short answer if you can ❤️*
