Energy may change in form or be transferred from one system to another, but the total remains the same. When all forms of energy are considered, conservation of energy is written in equation form as KEi+PEi+Wnc+OEi=KEf+PEf+OEf, where OE is all other forms of energy besides mechanical energy.

It discusses electrochemistry, which converts chemical to electrical energy, seen in batteries. It highlights that direct redox reactions, like those between zinc and copper ions, require separation into oxidation and reduction to perform work in electrochemical cells. These cells feature a solution for reactions, a conductor for electron transfer, and a salt bridge for ion movement.

It describes a voltaic cell, an electrochemical device that generates electrical energy via spontaneous redox reactions, including its two half-cells: the anode, which undergoes oxidation (losing zinc), and the cathode, which undergoes reduction (gaining copper).
