What is responsible for the chemical reaction inside a battery?

Hi,

 

 

A cell has three main parts: a positive electrode (terminal), a negative electrode, and a liquid or solid separating them called the electrolyte. When the two terminals of a battery are connected with wire, a circuit is formed.

A chemical reaction takes place in the electrolyte causing ions to flow through it one way,  flowing through the outer circuit in the other direction. This movement of electric charge makes an electric current flow through the cell and thus through the circuit.

Electrons will flow through the wire and electricity is produced. Inside the battery, a reaction between chemicals take place. But the reaction takes place only if there is a flow of electrons

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
