A strong acid OR base is one that:
kupik [55]

Answer: completely (100%) dissociates, producing a significant amount of H+ and OH- ions in solution, making it conduct electricity well.

Explanation:

A strong acid is one that ionizes or dissociate completely in water to yield its hydrogen ion (H+) as the only positively charged ion.

For example: Hydrochloric acid (HCl) dissociates completely in water to give hydrogen ion and chlorine ion

HCl(aq) --> H+(aq) + Cl-(aq)

A strong base, on the other hand, dissociates completely in water to yield an hydroxyl ion (OH-) as the only negatively charged ion. A good example is Sodium hydroxide NaOH

NaOH (aq) --> Na+(aq) + OH-(aq)

And since mobile and charged ions help transmit electric current, a strong acid or base produces significant amount of H+ and OH- ions that conduct electricity well.

What is the electron geometry if you have 4 electron groups around the center atom? What is the electron geometry if you have 4
nadya68 [22]

Answer:tetrahedral

Explanation:

According to Valence Shell Electron Pair Repulsion Theory (VSEPR). The number of electron pairs on the valence shell of the central atom in a molecule influences the shape of that molecule. Four electron pairs around the central atom of a molecule leads to a tetrahedral geometry as predicted by VSEPR.

Carbon and fluorine have the same shielding effect<br><br> True or False
iragen [17]

Answer:

true

Explanation:

There are two electrons (in the 1s orbital) on both carbon and fluorine “shielding” the outer electrons from the full force of the nucleus and due to both atoms being approximately the same size (both period two) then it is this shielding effect and proton difference that is causing the electronegativity difference

· Explain electromeric effect.​
Marianna [84]

Answer:

Electromeric effect refers to a molecular polarizability effect occurring by an intramolecular electron displacement (sometimes called the 'conjugative mechanism' and, previously, the 'tautomeric mechanism') characterized by the substitution of one electron pair for another within the same atomic octet of electrons.
