To solve this problem, let's analyze the reaction.
In the production of hydrochloric acid (HCl), each molecule of HCl is made up of one hydrogen atom and one chlorine atom. If 20 molecules of HCl are produced, it means that:
- 20 hydrogen atoms (H) reacted.
- 20 chlorine atoms (Cl) are required to produce those 20 molecules of hydrochloric acid.
According to the law of conservation of matter, the number of atoms must be the same on both sides of the equation. Therefore, if 20 hydrogen atoms reacted, then 20 chlorine atoms must also have reacted.
Thus, the answer is **20**.
