- I need help with the final question which is in bold. The previous questions and answers are needed to answer the final question In an electrolysis experiment similar to the one employed this experiment; a student observed that his unknown metal anode lost 0.238 grams while a total volume of 94.50 mL of hydrogen was being produced. The temperature of the solution was 25oC and the barometric pressure was 739 mm Hg. The difference between the water levels in the beaker and buret was negligible. The vapor pressure of water at 25oC is 23.8 mm Hg. Based on the information provided and the lab handout, what pressure of hydrogen is collected, in atmospheres? 9.41x10^-1 atm Using the data collected (in the previous problem), calculate the moles of hydrogen collected. 3.63x10^-3 mol Upon electrolysis, the metal is oxidized to a 2+ valence state. Based on this information, how many moles of metal are present? 3.63x10^-3 mol Use the mass of metal lost and moles from the previous problem to…arrow_forwardUse the given galvanic cell notation below to answer the following questions. 2+ Sn (s) | Sn²+ (aq) || Ti+ (aq)| Ti (s) a) Write the oxidation half reaction.

- In electrochemistry, what kind of reaction can be driven by electricity?arrow_forwardA student made measurements on some electrochemical cells and calculated three quantities: • The standard reaction free energy AGº. • The equilibrium constant K at 25.0 °C. • The cell potential under standard conditions E". His results are listed below. Unfortunately, the student may have made some mistakes. Examine his results carefully and tick the box next to the incorrect quantity in each row, if any. Note: If there is a mistake in a row, only one of the three quantities listed is wrong. Also, you may assume the number of significant digits in each quantity is correct. Also note: for each cell, the number n of electrons transferred per redox reaction is 1. calculated quantities (Check the box next to any that are wrong.) cell n aG K E -21 1.42 x 10 A 1 119. kJ/mol O 1.23 V -- В - 51. kJ/mol 1.16 X 10 -0.53 V -11 2.06 X 10 1 -61. kJ/mol 0.63 Varrow_forward
