Explanation:
Resonance is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by a single Lewis formula. A molecule or ion with such delocalized electrons is represented by several resonance structures(Chemlibretexts).
Azulene, an isomer of naphthalene is an aromatic hydrocarbon whose structure has been shown in the image attached to this answer. Usually, charge separation decreases the stability of a resonance structure.
As a result of this charge separation in azulene, Naphthalene is more stable than azulene.
Acetic acid (CH3COOH) reacts with water to form the acetate ion and the hydronium ion:
At equilibrium, the concentration of CH3COOH is 2.0 × 10–1<span> M, the concentration of CH</span>3COO–<span> is </span>
1.9 × 10–3<span> M, and the concentration of H</span>3O+<span> is 1.9 × 10</span>–3<span> M. What is the value of </span>Keq<span> for this reaction?
1.8 * 10^-5</span>
Answer:
In fact, science helps a lot for social, political, ethical, and economic problems. Your question is just to deny that science is not helping your life and you have no evidence to support what you say.
