MCQ
The net ionic equation that gives nearly the same heat of neutralization for all strong acid-strong base pairs is:
Unit-8 Energetics
A H+ (aq) + OH- (aq) -> H2O (l)
B HCl + NaOH -> NaCl + H2O
C H2 + Cl2 -> 2HCl
D Na + H2O -> NaOH + H2
Explanation

All strong acid-strong base reactions release the same heat because only H+ and OH- combine to form water.
