In acid solution, water can add to the double bond of 2‑butenedioic acid to form 2‑hydroxysuccinic acid.
Art [367]

Answer:

Explanation:

The stereochemical structures of the two compounds of the fumarase-catalyzed reaction are in the attachment below. The reaction been referred to is illustrated in the equation below

HOOCCH=CHCOOH + H₂O ==> HOOCCH₂CH(OH)COOH

The compounds attached are trans-2-butenedioate (which is one of the reactants) and (s)-2-hydroxysuccinate (which is the product formed)

Note that stereoisomers are isomers that differ in spatial orientation, thus there are other isomers that could contain the same atoms and have slightly but different spatial orientation such as cis-2-butenedioate and (r)-2-hydroxysuccinate

Which Of the following, the best explanation for the fact that most gases are easily compressed is that the molecules in a gas a
Otrada [13]

Answer: A. are relatively far apart

Explanation:

Compressbility is the ability of compound to reduce in size when pressure is applied.

Gaseous state is a state in which the particles are loosely arranged and have a lot of space between them. Thus molecules can be easily compressed.

They have highest kinetic energy. This state has indefinite volume as well as shape.  The molecules in the gaseous state move faster with an increase in temperature as the kinetic energy increases with increase in temperature.

Thus most gases are easily compressed is that the molecules in a gas are in constant motion are relatively far apart.

A solution is made by dissolving 15.5 grams of glucose (C6H12O6) in 245 grams of water. What is the freezing point depression of
sergij07 [2.7K]
From the equation; ΔTf = Kf × m
Where, Kf for water = 1.853 K kg/mole; m is the molarity = number of solute/amount of solvent in kg.
Glucose is the solute whose molecular mass is 180 g/mole and water is the solvent. 
Moles of solute = 15.5/180 = 0.0861 moles
Amount of solvent in kg = 245/1000 = 0.245 Kg
Therefore; molarity = 0.0861/0.245 = 0.3515 moles/Kg
Therefore; ΔTf = 1.853 × 0.3515 = 0.6513 K
Hence; the depression in freezing point is 0.6513 
The freezing point of solution will therefore be;
= 273 - 0.6513 = 272.3487 K
