Answer:

-152.92°C

Explanation:

Initial volume = 0.750 mL

Initial temperature = -32.7 °C (-32.7 + 273.15 K = 240.45 k)

Final temperature = ?

Final volume = 0.750 mL / 2= 0.375 mL

Solution:

The given problem will be solve through the Charles Law.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

T₂ = T₁V₂ / V₁

T₂ = 240.45 k × 0.375 mL / 0.750 mL

T₂ = 90.17 mL.K / 0.750 mL

T₂ = 120.23 K

Temperature in celsius:

120.23 K - 273.15 = -152.92°C

At 25 ∘C only 0.0180 mol of the generic salt AB is soluble (at equilibrium) in 1.00 L of water.What is the value for Ksp for thi

Ghella [55]

Answer:

Ksp = 3.24 x 10⁻⁴

Explanation:

The dissociation equilibrium for a generic salt AB is:

AB(s) ⇄ A⁺(aq) + B⁻(aq)

s s

For instance, the expression for the Ksp constant is:

Ksp = [A⁺] [B⁻] = s x s = s²

According to the problem, 0.0180 mol of the salt is soluble in 1.00 L os water. That means that the solubility of the salt (s) is equal to 0.0180 mol per liter.

s = moles of solute/L of solution = 0.0180 mol/L

Thus, we calculate Ksp from the s value as follows:

Ksp = s² = (0.0180)² = 3.24 x 10⁻⁴

Answer:

When an electron moves from a higher to lower orbital, energy is released as waves of light.

Explanation:

The energy from the flame excites the electrons to orbitals of higher energy.

When the electrons drop to lower-energy orbitals, they release the excess energy as light waves.

This compound, (C10H12O3), shows strong, sharp absorption between 1700 and 1720 cm-1, and strong, broad absorption over the regi

Kruka [31]

Answer:

Explanation:

The peak at 1700-17200 cm⁻¹ in the infrared spectrum shows the existence of a carbonyl group (C=O). The appearance of an OH peak is shown by the broad peak at 2500-3000 cm⁻¹. The peak at 12.4 ppm in 1H NMR identifies the existence of carboxylic acid. The peaks at 6.78 ppm and 7.11 ppm suggest that the prevalence existence of a benzene ring in the molecule. Because these peaks are doublets, the benzene is being para-substituted.

The existence of the CH2 group is shown by the peak at 2.49 ppm, which integrates 2 hydrogens. Provided that the breaks are doublets, It would be bound to another CH2 molecule as well as carbon that is devoid of hydrogen (benzene carbon).

The existence of the CH2 group, which is linked to the above-listed CH2 group, is also demonstrated by the next peak at 2.8 ppm. It must be bonded with carbonyl carbon so it breaks as a doublet. As a result, it has a greater chemical transition. The CH3 category is shown by the peak at 3.72 ppm. Its chemical change is strong, indicating that CH3 is linked to an oxygen atom that is linked to benzene.

NMR details at 13C. Carbonyl carbon of acid has a high (peak) at 173.89 ppm. Benzene carbon peaks range from 113.55 to 157.87 ppm. The peak at 64 is made up of CH3, while the other two are made up of CH2.

The structure of the diagram is shown below with its degree of unsaturation.
