Suppose 20 atoms of hydrogen (H) react with chlorine (Cl) to produce 20 molecules of hydrochloric acid (HCl). According to the law of conservation of matter, how many atoms of chlorine reacted with the hydrogen
If it is HCl, then itv would take 20 atoms of Cl to combine with H to get HCl
didnt even help noob

Well, 20 atoms of hydrogen react with 20 molecules of chlorine. But here's the catch, each molecule of chlorine is made up of 2 atoms of chlorine (Cl). So, in total, we have 20 x 2 = 40 atoms of chlorine that reacted with the hydrogen. That's a whole Cl-razy amount of atoms reacting there!
To find out how many atoms of chlorine reacted with the hydrogen, we need to determine the balanced chemical equation for the reaction between hydrogen and chlorine.
The balanced chemical equation for the reaction between hydrogen (H2) and chlorine (Cl2) to produce hydrochloric acid (HCl) is as follows:
H2 + Cl2 → 2HCl
This equation shows that 1 molecule of hydrogen reacts with 1 molecule of chlorine to produce 2 molecules of hydrochloric acid.
Given that 20 molecules of hydrochloric acid were produced, we know that there were 20/2 = 10 molecules of chlorine that reacted.
Since each chlorine molecule (Cl2) consists of 2 chlorine atoms (Cl), the number of chlorine atoms involved in the reaction is 10 x 2 = 20 chlorine atoms.
Therefore, 20 atoms of chlorine reacted with the hydrogen.
