a. For the electrolysis of molten BaCl2, diagram a cell. Include the direction in which a battery would be placed to power the cell. Write out half-reactions. Label flow of electrons, anode, cathode, indicate what is formed at each electrode (assume electrodes are generic metal). Could this reaction be carried out in aqueous solution? Why or why not (justify numerically). b. 0.67 g of Ag is deposited electrolytically from AgNO3after a certain period of time when subjected to a 12A...

Objective: Identify types of corrosion and calculate quantities associated with corrosion. Part I: Uniform Corrosion The rate of uniform corrosion can be determined from the following equation, where CPR is the corrosion penetration rate in thickness lost per time. IM CPR = AnpF VA current density over the area which is losing the thickness area over which the material is being lost corrosion current number of electrons involved in the unbalanced oxidation half-reaction (not the number of electrons in the...

Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!
