Answer:
The net ionic equation is
H₃O⁺+NH₃ ↔ NH₄⁺+H₂O
Explanation:
To write the net ionic equation, we are required to dissociate the into ions all strong acids and strong bases
Hence, nitric acid which is a strong acid is dissociated as follows
HNO₃+H₂O → H₃O⁺ + NO₃⁻
in the above equation, the nitrate ion NO₃⁻, is a spectator ion because it is only present and does not partake in the chemical reaction so it is left out of the net ionic equation equation
Also the it is required to keep together weak bases in the solution therefore for NH₃ which is a weak base we have
NH₃ + H₃O⁺ → NH₄⁺ + H₂O
Hence, the net ionic equation becomes
H₃O⁺ (aq) + NH₃ ↔ NH₄⁺(aq) + H₂O (l)

Answer:
Micelle Formation
Explanation:
The soap molecule has a nonpolar and a polar cationic end when it is dissolved in water. When it dissolves in water, the sodium stearate congregates to form small spheres (called micelles) with the on the inside and the on the surface. The anionic end can attract and interacts with the polar water molecules, while the interact with the nonpolar grease. This allows the soapy water to remove the grease by trapping the grease inside the micelle.
