Question

Atomicity of C2H6, He and
HCl is

Answer 1

Answer: HOPE THIS HELPS YOU, PLEASE MARK BRAINLIST AND THANK.

Explanation: C2H6=The atomicity of C2H6 is 8

Because atomicity is the number of atoms present in one molecule..

C=2 carbon atom

H=6 hydrogen atom

=8 IS ATOMICITY

(ii) Helium =1 is atomicity here.            

(iii) HCl is made up of two atoms: 1 atom of Hydrogen and 1 atom of Chlorine. So, the atomicity of HCl= 2.
