Al + CuCl2 = AlCl3 + Cu

Balanced Chemical Equation – Solution

2Al + 3CuCl2 → 2AlCl3 + 3Cu

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

Aluminium + Tolbachite = Aluminum Chloride + Copper

This is an oxidation-reduction (redox) reaction. CuCl2 is an oxidizing agent, Al is a reducing agent.
