What are the components of a voltaic cell?

• The anode is an electrode where oxidation occurs.

• The cathode is an electrode where reduction occurs.

• A salt bridge is a chamber of electrolytes necessary to complete the circuit in a voltaic cell.

• The oxidation and reduction reactions are separated into compartments called half-cells.

•The external circut is used to conduct the flow of electrons between the electrodes of the voltaic cell and usually includes a load.

• The load is the part of the circuit which utilizes the flow of electrons to perform some function.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
