Answer:
2 mL of Solution A must be added to Solution B to give a buffer that is equimolar.
Explanation:
Given the data in the question;
First we determine the number of sodium acetate;
⇒ molarity × volume ( L )
⇒ 0.16 × 2.0 mL
⇒ 0.16 × 0.002 L
⇒ 0.00032
Now, Molarity of sodium acetate = moles / Volume(L)
⇒ ( 0.00032 / 50 ) × 1000
⇒ 0.0064
Since number of moles of acetic acid that should be added tp make equimolar solution is 0.00032
and Molarity of acetic acid is 0.16 molL⁻¹
Let X represent the volume that should be added.
so;
Molarity = Moles / Volume (L)
we substitute
0.16 = (0.00032 / X) × 1000
0.16 = 32 / X
X = 0.32 / 0.16
X = 2 mL
Therefore, 2 mL of Solution A must be added to Solution B to give a buffer that is equimolar.
The answer must be 50ml cos volume means the amount or space an object occupies and the final result is 50

Answer with Explanation:
Small and large carbohydrates have<em> diverse structural properties</em>. Such property allow them to have <u>different solubility.</u>
Solubility is a chemical property of a substance that allows it to dissolve in a given solvent.
Carbohydrates are made up of "monosaccharides." These are simple sugars and are considered small carbohydrates. On the contrary, "polysaccharide" is an example of a large carbohydrate.<em><u> Monosaccharides are soluble in water</u></em><em> </em>while<em><u> many polysaccharides are not soluble in water.</u></em>
The high solubility of monosaccharides is mainly due to the presence of hydroxide (OH) groups. These groups are always ready to bond with water (H₂O). Many polysaccharides are not soluble in water because of <em>intermolecular interactions</em> that prevents it from binding with water. Its dissolution process is different when compared to the smaller molecules.
So, this explains the answer.
