What is the complete ionic equation for
NaOH(aq) + HCl(aq) → H2O(1) + NaCl(aq)

OH⁻ (aq) + H⁺ (aq) → H₂O (l)

General Formulas and Concepts:

Chemistry

Explanation:

Step 1: RxN

NaOH (aq) + HCl (aq) → H₂O (l) + NaCl (aq)

Step 2: Balance RxN

Reaction is already balanced.

Step 3: Ionic Equations

Total Ionic Equation:

Break up the aqueous solutions into individual ions.

Na⁺ (aq) + OH⁻ (aq) + H⁺ (aq) + Cl⁻ (aq) → H₂O (l) + Na⁺ (aq) + Cl⁻ (aq)

Net Ionic Equation:

Remove spectator ions.

OH⁻ (aq) + H⁺ (aq) → H₂O (l)

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
