Answer 1

To determine how many atoms of chlorine reacted with the 20 atoms of hydrogen to produce 20 molecules of hydrochloric acid (HCl), we need to consider the molecular composition of HCl.

Each molecule of HCl consists of one hydrogen atom and one chlorine atom. Since we are producing 20 molecules of HCl, we can deduce the following:

• Each molecule of HCl requires 1 hydrogen atom and 1 chlorine atom.
• Therefore, to produce 20 molecules of HCl, 20 hydrogen atoms will react with 20 chlorine atoms.

So, the answer is that 20 atoms of chlorine reacted with the 20 atoms of hydrogen.

Thus, the correct response is:

20
