Answer:
The United States customary system aka USCS or USC?
A. conduction
that is the correct answer
The balanced chemical reaction is:
HNO3 + NaOH = NaNO3 + H2O
We are given the amount and concentration of the reactants. The values given will be the starting point.
0.20 mol /L HNO3 (.015 L) (1 mol NaOH / 1 mol HNO3) = 0.003 mol NaOH
0.003 mol NaOH / 0.10 mol/ L NaOH = 0.03 L NaOH or 30 mL NaOH

Explanation:
When a salt is dissolved in water, the solution could be acidic, basic or neutral depending on the nature of acid and base from which the salt was formed.
When a salt is formed from a strong acid and a weak base, the salt solution is acidic.
For instance, NH4Cl is a salt formed from NH3 which is a weak base and HCl which is a strong acid. The salt hydrolyses as follows;
NH4^+(aq) + H2O(l) ------> H3O^+(aq) + NH3(aq)
Hence an acidic solution is formed.
