Balanced Chemical Equation – Solution
2Al + 6HCl → 2AlCl3 + 3H2
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
Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water
This is an oxidation-reduction (redox) reaction. HCl is an oxidizing agent, Al is a reducing agent.
- 6 HI + 6 e– → 6 H0 (reduction)
- 2 Al0 – 6 e– → 2 AlIII (oxidation)
