Thought cannot be performed or produced by a cell as it is devoid of a capable nerve system and hence it does not get any information and thus cannot produce any thought.
The information given in the question is not enough to determine the acidity of the solution. This is because, acidity can only be found with the equation: pH = -log [H+].
In order to determine the acidity of the solution, the half titration point value is needed, this will make it possible to determine the value of H30+. If the half point titration value is known, then Ka will be equivalent to pH and the value will be evaluated using the equation: - log (1.6 * 10^-10).
S2F10, FE3N2, S7O2, NaCO3, Al2O3, PC13, and CO2. Hope this helps
I would say D. Let me know if i am wrong.
