<u>Answer:</u> The correct statement is the metalloids are located below nonmetals and above metals within a group.

<u>Explanation:</u>

Metalloids are the chemical elements which shoe the property of both metals and non-metals. There are 7 metalloids in the periodic table: Boron (B), Silicon (Si), Germanium (Ge), Arsenic (as), Antimony (Sb), Tellurium (Te) and Polonium (Po).

These elements are located right to the metals and left to the non-metals in a period and they lie above the metals and below the non-metals in a group.

Hence, the correct statement is the metalloids are located below nonmetals and above metals within a group.

The metalloids are Boron, Silicon, Geranium, etc and are found to the right of the metals and the left of the nonmetals. Since that is not an option, the best choice would be: The metalloids are located below nonmetals and above metals within a group.

Calculate the pOH of an aqueous solution of .0.073 M LiOH
Novosadov [1.4K]

Considering the definition of pOH and strong base, the pOH of the aqueous solution is 1.14

The pOH (or potential OH) is a measure of the basicity or alkalinity of a solution and indicates the concentration of ion hydroxide (OH-).

pOH is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:

pOH= - log [OH⁻]

On the other hand, a strong base is that base that in an aqueous solution completely dissociates between the cation and OH-.

LiOH is a strong base, so the concentration of the hydroxide will be equal to the concentration of OH-. This is:

[LiOH]= [OH-]= 0.073 M

Replacing in the definition of pOH:

pOH= -log (0.073 M)

<u><em>pOH= 1.14 </em></u>

In summary, the pOH of the aqueous solution is 1.14
