PH = -log[H+] therefore lower pHs contain more H+ ions, so Jack's soup contains more free H+. Since pH is a logarithmic scale and Jack's soup has a pH of 2 less than Charlie's, it contains 10^2 = 100 times more H+ ions.
It would be group 1 because of hydrogen but since it's not there the other group is group 14.

Explanation:
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years..
M = n / V
M = 0.5 / 0.05
M = 10 mol/L-1
