Acell is built using two electrodes: what reaction occurs at the cathode?
al3+ + 3e —> al e° = -1.66v
cu2+ + 2e —> cu e° = +0.34v

a. cu —> cu2+ + 2e-
b. cu2+ + 2e- —> cu
c. al3+ + 3e- —> al
d. al —> al3+ + 3e-

1. and 2. question: in which equation? or i don't understand you, 3. a), 4. c), 5. c), 6. b), 7. d), 8. d) if small number is underlined(behind symbol) , b) if big number is underlined(in front of symbol)9. what is underlined there? 10. c)

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom.
