<span>The kinetic </span>theory of matter<span> (</span>particle theory<span>) says that all </span>matter<span> consists of many, very small </span>particles<span> which are constantly moving or in a continual state of motion. The degree to which the </span>particles<span> move is determined by the amount of energy they have and their relationship to other </span><span>particles</span>
When the acid is hydrolyzed, the reaction is
HA --> H⁺ + A⁻
So,
Ka = [H⁺][A⁻]/[HA]
Apply the ICE approach:
HA --> H⁺ + A⁻
I 0.3 0 0
C -X +X +X
E 0.3-X X X
Ka = [X][X]/[0.3-X]
X = H⁺ = A⁻
The formula for pH is:
pH = -log[X]
5.2 = -log[X]
Solving for X,
X = 6.31*10⁻⁶
Therefore,
Ka = [6.31*10⁻⁶][6.31*10⁻⁶]/[0.3-6.31*10⁻⁶]
<span>Ka = 1.33×10⁻¹⁰</span>

Answer:
Covalent bond
Explanation:
A chemical bond formed when two atoms share one or more pairs of electrons with each other. Double bond: A covalent bond consisting of two pairs of electrons. Electronegativity : A numerical method for indicating the relative tendency of an atom to attract the electrons that make up a covalent bond.
