<span>Have you ever seen a buoy on a sea before? It goes up and down, perpendicular to the direction the wave moves. What's the motion of the sea looks like? Transverse wave, not ocean waves because we're talking about particles.</span>
Answer
Hi, the correct answer is,
B. It is an acid-base reaction because the sodium hydroxide base reacts with the hydrochloric acid to form a salt and water
Explanation
When an acid reacts with a base, the products are salt and water.In this case, sodium hydroxide is a base which contains hydroxide ions, OH-, whereas hydrochloric acid is an acid that has Hydrogen ions, H+.When they react, they form sodium chloride, NaCl in aqueous solution as the salt , and additional water molecules. The equation is;
NaOH (aq) + HCl (aq) → NaCl (aq) + H2O (l)

Explanation:
Precipitation:
Ag (aq) + HCl (aq) → H₂ (g) + AgCl↓
Precipitation reactions can contain a single element.
Certainly, two soluble solutions are mixed, forming an insoluble solid.
Reactions can be identified using a solubility chart, because solubility can affect the precipitacion's equilibrium.
Acid base:
Certainly you mix an acid(H+) an a base (OH-)
We talk about neutralization because we make water. And, there is also a formed salt.
HNO₃ + KOH → H₂O + KNO₃
H⁺ + OH⁻ ⇄ H₂O Kw
Redox:
This is the reaction where moles of electrons are transferred and gained.
A pure element is consumed or formed. We have 2 half reactions:
- Reduction (oxidation state decreases, electrons are released)
- Oxidation (oxidation state increases, electrons are gaines)
Reactions involving pure O₂ are named combustion, which is a redox type.
This is an example of redox decomposition of hydrogen peroxyde.
2H⁺ + H₂O₂ + 2e⁻ → 2H₂O
H₂O₂ → 2H⁺ + O₂ + 2e⁻
H₂O₂ → 2H₂O + O₂
