Answer the following questions based on the following electrochemical reaction: Al(s) + Cu 2+(aq) <====> Cu(s) + Al3+ (aq) Write the balanced chemical equation for this cell. I'm confused.. how would this be balanced?

Calculate the free energy in a saturated solution of Ca(OH)2 if the Ksp =6.5x10-6 at 25 degrees Celsius. sorry to be a bother but I don't understand how to do this problem either.. can someone please explain this one to me as well?

I've been searching my chemistry book for hours and I can't find much on cell potential... I also tried watching youtube videos but I still can't figure it out... help would be appreciated.
