The equation is B2O3 + 6HCl -> 2BCl3 + 3H2O.

Detailed information about the chemical equation B₂O₃ + 6HCl -> 2BCl₃ + 3H₂O:
The equation represents the chemical reaction process of boric oxide (B₂O₃) and hydrochloric acid (HCl) to produce boron trichloride (BCl₃) and water (H₂O).

Reaction conditions:
The reaction usually occurs at high temperatures. HCl needs to be used in vapor form for the reaction to effectively take place.

Reaction process:
When B₂O₃ and HCl are introduced under suitable conditions, B₂O₃ molecules will react with HCl molecules. At this point, B₂O₃ molecules will receive Cl from HCl and form BCl₃. HCl, after giving Cl, will become H₂O.

Occurring phenomena:
During the reaction process, there will be changes in color and temperature. Specific phenomena can vary depending on the conditions and reaction environment.
