Balanced Chemical Equation – Solution
Al2O3 + 6HCl → 2AlCl3 + 3H2O
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
This is an acid-base reaction (neutralization): Al2O3 is a base, HCl is an acid.
Ruby + Hydrogen Chloride = Aluminum Chloride + Water
Reaction Type
Double Displacement (Metathesis)
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
