Which of the following pairings of pH and hydronium ion concentration is correct? A: pH = 7.0; [H3O+] = 1 x10^–7

B: pH = 2.0; [H3O+] = 1 x10^2

C: pH = 9.0; [H3O+] = 9 x10^–9

D: pH = 3.0; [H3O+] = 3 x10^–11

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

: )

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
