Chem 1212 Lab Report on electrochemistry Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...

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!! Equivalent Mass by Electrolysis If the two terminals on any source of DC...
