B.
This method of expressing concentration is employed with solutions where both the solute and solvent are liquid. This is because it is easy to measure the volume of a liquid compared to that of a solid. Usually weight/weight is used in concentrations involving only solids.

I believe the correct response would be D. Solutions with a liquid solvent and a solid solute. This is primarily for concentrations measured in terms of number of moles/volume.

On the basis of the information above, a buffer with a pH = 9 can best be made by using
telo118 [61]

Answer:

D H2PO4– + HPO42–

Explanation:

The acid dissociation constant for \mathbf{H_3PO_4 , H_2PO^{-}_4 ,  HPO_4^{2-}} are \mathbf{7\times 10^{-3}, \ \ 8\times 10^{-8} ,\ \  5\times 10^{-13}} respectively.

\mathbf{pka (H_3PO_4) = -log (7\times 10^{-3} )=2.2}

\mathbf{pka (H_2PO_4^-) = -log (8\times 10^{-8} )=7.1}

\mathbf{pka (HPO_4^{2-}) = -log (5\times 10^{-13} )=12.3}

The reason while option D is the best answer is that, the value of pKa for both

\mathbf{H_2PO^{-}_4 ,\  \& \  HPO_4^{2-}} lies on either side of the desired pH of the buffer. This implies that one is slightly over and the other is slightly under.

Using Henderson-Hasselbach equation:

\mathbf{pH = pKa + log \Big( \dfrac{HPO_4^{2-}}{H_2PO_4^-} \Big)}

What’s are the different Types of chemical weathering
Ira Lisetskai [31]

Answer:

Types of chemical weathering

1. Hydrolysis

2. Oxidation

3. Carbonation

4. Acid rain

5. Acids produced by lichens

Explanation:

Chemical weathering occurs when rocks undergo chemical reactions to form new minerals.

Hydrolysis : is when water dissolves minerals present in rocks forming new compounds.

Oxidation : is when oxygen reacts with rocks eg. rust formation

Carbonation : it uses an acid known as carbonic acid, it is important in the formation of many caves and sinkholes.
