The net ionic equation is as below

H^+(aq) + H^-(aq) → H2O(l)

Explanation
from the chemical equation

HClO4(aq) + NaOH (aq) → H2O(l) + NaClO4(aq)

write ionic equation
that is,
H^+(aq)+ClO4^-(aq) + Na^+(aq) +OH^-(aq)→ H2O(l) + Na^+(aq)+ClO4^-(aq)

cancel the spectator ions in both side(ions that do no take place in a chemical equation)
that ClO4^- and Na^+

the net ionic is therefore
= H^+(aq) + OH^-(aq) → H2O(l)

Answer from: 19wawrzkeek

The net ionic equation is defined as the removing spectator ions from total equation and list the species that only participate in the reaction. In the given equation, $\text {HClO}_{4}_{(aq)}+\text{NaOH}_{(aq)}\rightarrow\text{H}_{2}\text O_{(l)}+\text {NaClO}_{4}_{(aq)}$ , the net iconic equation will be:

$H^{+}_{(aq)} + \text{OH}^{-}_{(aq)}\rightarrow \text{H}_{2}\text{O}_{(l)}$

In aqueous solution, HClO $_{4}$ will dissolve into H $^{+}$ and ClO $_{4}^{-}$ . Similarly, NaOH will be dissociated into Na $^{+}$ and OH-. The resultant salt formed is NaClO $_{4}$ . The equation can be expanded as:

$\text {HClO}_{4}_{(aq)}+\text{NaOH}_{(aq)}\rightarrow\text{H}_{2}\text O_{(l)}+\text {NaClO}_{4}_{(aq)}\\\\\text {H}^{+} + \text {ClO}_{4}^{-} + \text {Na}^{+} + \text {OH}^{-}\rightarrow \text{H}_{2}\text {O} + \text{Na}^{+}+ \text {ClO}_{4}^{-}$

Thus, cancelling out the terms on both sides of the equation, those are termed as spectator ions. The spectator ions are:

$\text {H}^{+} + \text {ClO}_{4}^{-} + \text {Na}^{+} + \text {OH}^{-}\rightarrow \text{H}_{2}\text {O} + \text{Na}^{+}+ \text {ClO}_{4}^{-}$

Remaining, net iconic equation is:

$H^{+}_{(aq)} + \text{OH}^{-}_{(aq)}\rightarrow \text{H}_{2}\text{O}_{(l)}$

Therefore, for any strong acid and strong basic reaction, the net ionic reaction is the neutralization of Hydrogen and Hydroxide ions to form water.

Answer from: Quest

The correct answer is c

Answer from: Quest

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
