Question

1) Mention any one point of difference between Pepsin and Trypsin.
2) An element “X” has mass number 35 and the number of neutrons, is 18. Identify the group number and period of “X”.

Answer 1

Hey,
1)Pepsin is produced in the stomach and acts in an acidic medium ,while trypsin is produced by the pancreas and acts in a basic medium.
2)Mass no. =35
No. of neutrons =18
Therefore,
No. of protons =Mass no. - no. of neutrons
=35-18
=17.(Element X is Chlorine)
So, Group number is group 17(Halogens) and
Period number is 3.
Hope this helps you buddy!!
