A neutral solution has a pH of: 7
Answer choice B.
Answer:
pKb = 5
Explanation:
To find the pKb, you need to (1) calculate the pka (using the pKa equation) and then (2) calculate the pKb (using the relationship between the pKa and pKb).
(Step 1)
pKa = -log (Ka)
pKa = -log (1 x 10⁻⁹)
pKa = 9
(Step 2)
pKa + pKb = 14
9 + pKb = 14
pKb = 5

An example of an extensive property of matter is mass , it is the amount of matter in a body. To measure it is used, as with weight, the kilogram. It is a scalar magnitude. there other examples of extensive property such as weight, volumen, length, potential energy, heat capacity and inertia.
<h2>Answer:</h2>
In the periodic table, the elements of the same group and elements of the same column, have similar reactivity because they have a similar configuration in their valence electrons.
There are some factors which determine the chemical properties if an element of the periodic table.
- No. of arrangement of electron in an atom.
- No. of valence electrons.
- Arrangement of electrons.
