This equation shows the reaction between hydrochloric acid (HCl) and calcium chloride (CaCl2), calcium nitrate (Ca(NO3)2), calcium carbonate (CaCO3), and calcium sulfate (CaSO4).

2HCl + CaCl2 = Ca(NO3)2 + CaCO3 + CaSO4

This equation is not balanced as the number of atoms of each element on both sides of the equation is not equal. The balanced equation for this reaction would depend on the specific amounts of reactants and conditions of the reaction.
