Explanation:
Answer:
C. pH values are different because the 
solution partially ionizes and the HCl solution ionizes 100 percent.
Explanation:
Strong acids are the acids which completely ionizes in the solution while weak acids are the acids which ionizes partially in the solution. They exists in equilibrium in the solution with their respective ions.
Thus, strong acids furnish greater concentration of protons as compared to weak acid when same concentration of both types are taken.
<u>Also, pH is the negative of the logarithm of the hydrogen ions. Thus, hydrogen ion concentration for both acids are different and thus pH will be different.</u>

Answer:
The correct answers are:
"Only about 3 percent of Earth's water is fresh water."
"About 75% percent of the fresh water on Earth is frozen in ice sheets."
"The largest source of usable fresh water is groundwater."
Explanation:
3 percent of Earth's water is most certainly fresh water. Confirmed with a few fact checks.
The largest source of usable fresh water on Earth is groundwater. It's more difficult to access but it's there and much more usable than water say frozen in ice on the sea.
The most correct option left would be 75% of Earth's freshwater being in ice sheets even though it's about 70%.
The process is called, Fixation
