The chemical reactin is:
Ca + HCl = CaCl2 + H2
Ca + 2HCl --> CaCl2 + H2
Ca(OH)2 + 2 HCl -> CaCl2 + 2 H2O
Ca + 2HCl ==> CaCl2 + H2
2HCl + Ca -> CaCl2 + H2 (gas)
The reaction between calcium and water can be represented by the following balanced chemical equation: Ca + 2H2O → Ca(OH)2 + H2Ca + 2H2O → Ca(OH)2 + H2 In this equation: Calcium (CaCa) reacts with water (H2OH2O). Calcium hydroxide (Ca(OH)2Ca(OH)2 ) is formed. Hydrogen gas (H2H2) is also produced. This balanced equation ensures that the number of atoms for each element is the same on both sides of the equation, indicating that mass is conserved in the chemical reaction.
2HCl + Ca(OH)2=CaCl2 +2H2O this is hydrochloric acid add ant acid = the symbol equation
THE REACTION OF 1 MOLE Ca WITH 2 MOLES OF HCL RESULTS IN TO FORMATION OF CALCIUM CHLORIDE & HYDROGEN GAS WILL LIBERATE.
Ca + 2H2O ==> Ca(OH)2 + H2
Ca + 2 HCl = CaCl2 + H2
2HCl + Ca -> CaCl2 + H2 (gas)
First write the balanced chemical equation for this reaction CaCO3+2HCl-->CaCl2+H2O+CO2 It is clear from this equation that one mol of HCl can react with half a mol of CaCO3. Thus, one half of .025 mols CaCO3 will react with .025 mols HCl. That makes .0125 mols CaCO3.

Ca + 2H2O ==> Ca(OH)2 + H2
Ca + 2 HCl = CaCl2 + H2
Though concentrated HCl might be an oxidant (H+), this is NOT a redox but an acid-base reaction (base or hydroxide comes from Ca(OH)2).
You could add hydrochloric acid to calcium to form calcium chloride and hydrogen gas. 2HCl + Ca → CaCl2 + H2
The balanced equation for the reaction between calcium hydroxide and hydrochloric acid is: Ca(OH)2 + 2HCl → CaCl2 + 2H2O In this reaction, calcium hydroxide (Ca(OH)2) reacts with hydrochloric acid (HCl) to produce calcium chloride (CaCl2) and water (H2O). The equation is balanced with 1 molecule of calcium hydroxide reacting with 2 molecules of hydrochloric acid to produce 1 molecule of calcium chloride and 2 molecules of water.
The reaction is; Ca(OH)2 + 2 HCl = CaCl2 + 2 H2O
