Answer:Ithink erosion cuz if we can tell how long ago it eroded we can see how old it is
Explanation:
Answer:
Option D. pH= 1.3 strong acid
From the question given:
The hydrogen ion concentration [H+] = 0.05 M
pH = —Log [H+]
pH = —Log 0.05
pH = 1.3
Since the pH lies between 0 and 7, the solution is acidic. Since the pH value is low, the solution is a strong acid
= 71.2 g
