(1) How many different types of HCl molecule can be produced from two natural isotopes of hydrogen `(""^(1)H=99% and ""^(2)H+1%)` and two natural isotopes of chlorine `(""^(35)Cl=76% and ""^(37)Cl=24%)`.
(2) Arrange the molecules obtained from (1) in the decreasing order of their availability.

Text Solution

Verified by Experts

(1) Four different types of HCl molecules can be produced.
They are - `""^(1)H^(35)Cl,""^(1)H^(37)Cl,""^(2)H^(35)Cl,""^(2)H^(37)Cl`.
(2) since the availability of `""^(1)H and ""^(35)Cl` are comparatively
`""^(2)H and ""^(37)Cl`, the decreasing order of their availability `""^(1)H^(35)Cl gt ""^(1)H^(37) Cl gt ""^(2)H^(35)Cl gt ""^(2)H^(37)Cl`.
