HCl+CaCO3 --> CaCl+H3O balanced?
No. It is not balanced.
There is no such thing as (neutral) H3O, nor is there any CaCl. The products should be H2O and CaCl2.
How did you get 3 H's in the products with only one H in the reactants? What happened to two of the three O atoms you started out with?
Tks. As I thought
