When hydrochloric acid (HCl) reacts with calcium hydroxide (Ca(OH)_2), the products formed are calcium chloride (CaCl_2) and water (H_2O). This is a typical acid-base neutralization reaction.

Here is the balanced chemical equation for the reaction:

[tex]\[ 2HCl + Ca(OH)_2 \rightarrow CaCl_2 + 2H_2O \][/tex]

1. Hydrochloric acid (HCl) provides hydrogen ions (H^+) and chloride ions (Cl^-).
2. Calcium hydroxide (Ca(OH)_2) dissociates into calcium ions (Ca^{2+}) and hydroxide ions (OH^-).
3. The hydrogen ions (H^+) from HCl combine with the hydroxide ions (OH^-) from Ca(OH)_2 to form water (H_2O).
4. The calcium ions (Ca^{2+}) from Ca(OH)_2 combine with the chloride ions (Cl^-) from HCl to form calcium chloride (CaCl_2).

Therefore, the correct answer indicating the products formed when HCl reacts with Ca(OH)_2 is:

[tex]\[ \text{CaCl}_2 \text{ and } \text{H}_2\text{O} \][/tex]
