Answer: Lactose
Explanation:
Lactose is a sugar present in milk is produced from the glycosidic linkage of galactose and glucose. The anomeric carbon atom of beta-galactose is attached to the 4th hydroxy group of glucose through beta-1, 4 glycosidic linkage.
Galactose an epimer of glucose is produced in the initial steps when glucose is activated by UDP to form UDP-glucose it can be epimerized to Galactose.
When a galactose subunit is combined with another glucose units through a glycosidic linkage it forms a disaccharide Lactose.
It’s going to take significantly less energy to heat Land V.S. Water. It’s also a different heat transfer process. Hope this helps
Answer:
pH = 9,32
Explanation:
The compound with 2 ionizable groups has the following equilibriums:
H₂M ⇄ HM⁻ + H⁺ pka = 6,2
HM⁻ ⇄ M²⁻ + H⁺ pka = 9,5
The reaction of M²⁻ with HCl is:
M²⁻ + HCl → HM⁻ + Cl⁻
The moles of M²⁻ are:
0,100L×1,0M = 0,1moles
And moles of HCl are:
0,060L×1,0M = 0,06moles
That means that moles of M²⁻ will be 0,1-0,06 = 0,04mol and moles of HM⁻ will be the same than HCl, 0,06mol
Using Henderson-Hasselbalch formula:
pH = pka + log₁₀ [M²⁻] / [HM⁻]
Replacing:
pH = 9,5 + log₁₀ [0,04] / [0,06]
<em>pH = 9,32</em>

Answer:
Unsaturated.
Explanation:
Hello,
In this case, since the solubility is useful to determine whether a solute will completely dissolve in a solvent or not, we must recall the solubility of potassium chloride at 50 °C that is 42.6 g per 100 g of water, it means that 42.6 g of KCl will completely dissolve in 100 g of water at such temperature. In such a way, since 14 g in the same mass of water is by far lower than the solubility at this temperature we can infer that the formed solution is unsaturated.
Best regards.
