Answer to Question #70985 in General Chemistry for John Ednilao

Question

Dihydrogen sulfide gas and chlorine gas are put at opposite ends of a 100 meter tube, both at 25 c. The chlorine gas is released and precisely 0.050 seconds later, the H2S is released. where along the tube will they meet?

The answer on the back of the book is 50.51 m from the Cl2 side, but I don't understand how they gotten that answer

Answer 1

Actually, the answer is not correct. The average velocity of Cl2 molecule is lower (298 m/s) than that of H2S molecule (431 m/s). Thus, Cl2 will travel 41 meter and H2S - 59 meters.
