How would the rate of disappearance of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution?.

Answers

Answer 1

C2H5Br(alc) + OH ‾(alc) → C2H5OH(l) + Br‾(alc)

The rate of disappearance of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution 1/4 the rate.

The liquid ether-like substance known as ethyl bromide is colourless, flammable, and has a burning flavour. On coming into contact with air and light, it turns yellowish. It can be found in gasoline and is utilised as a fumigant, solvent, and refrigerant.

Ethyl alcohol is the end product of the susbtitution reaction that occurs when ethyl bromide interacts with wet Ag2O. Methyl bromide is extremely poisonous. According to human studies, acute (short-term) methyl bromide inhalation can cause serious damage to the lungs.

Methyl bromide inhalation in humans can have neurological consequences both immediately after exposure and over time. Animal reports of neurological consequences have also been made.

in a mixture of gases with a total pressure of 15.0 bar, oxygen has a mole fraction of 0.41. what is the partial pressure of oxygen?

Answers

The partial pressure of oxygen would be 6.15 bar in a mixture of gases with total pressure of 15 bar, having oxygen the mole fraction of 0.41.

What is mole fraction and partial pressure and how the partial pressure comes out to be 6.15?Mole fraction is the ratio of number of components in one compartment to the total number of components present in a solution.Partial pressure is the individual pressure of a molecule in a mixture of molecules in a container.Here is given the total pressure that is P = 15 bar, and the mole fraction of oxygen that is X = 0.41.As we know the partial pressure of any gas can be calculated by multiplying the total pressure with mole fraction.15 bar x 0.41 = 6.15 partial pressure of O2, hence the partial pressure of oxygen in a mixture of gases would be 6.15 bar.

the molar solubility of manganese(ii) carbonate is 4.2 x 10-6 mol/l. what is the solubility product constant, ksp for manganese(ii) carbonate?

Answers

The molar solubility of manganese(ii) carbonate is 4.2 x 10-6 mol/l. what is the solubility product constant, ksp for manganese(ii) carbonate is 17.64 × 10⁻¹².

What is molar solubility?

Molar solubility (M) is a unit of measurement for a compound's capacity to dissolve in a particular liquid, also known as a solvent. Molar solubility is measured in terms of moles/L since it is the most moles of a solute that can dissolve in one liter of solvent. The solution is said to be saturated when it can no longer dissolve any more solute and the number of moles dissolved in a liter of solvent equals the molar solubility.

The ionization equation for MNCO₃ is given as:

MnCO₃ → Mn²⁺ + CO₃²⁻

Ksp=[Mn²⁺][CO₃²⁻]

From chemical reaction 1 moles of manganese and carbon reacts

than, molar solubility of MnCO₃ = 4.2 × 10⁻⁶ M

4.2 × 10⁻⁶moles of [Mn²⁺] reacts,

than it also reacts with 4.2 × 10⁻⁶ M of CO₃

Thus,

Ksp = (4.2 × 10⁻⁶) x (4.2 × 10⁻⁶)

Ksp = 17.64 × 10⁽⁻⁶⁺⁽⁻⁶⁾⁾

Ksp = 17.64 × 10⁻¹²

Why is it important for the surface area-to-volume-ratio of exchange surfaces to be maximized?.

Answers

It important for the surface area-to-volume-ratio of exchange surfaces to be maximized because it provides more space for the diffusion of gases.

Explain Adaptations of exchange surfaces?

In order to breathe, organisms must take in oxygen and expel carbon dioxide from their bodies. Since these gases spread across exchange surfaces like the lungs, exchange surfaces are modified to maximize diffusion.

A short diffusion pathway across the exchange surface is ensured by the fact that the majority of gas exchange surfaces are incredibly thin (sometimes only one cell thick). Additionally, they will have a high surface area to volume ratio, which creates greater room for gas diffusion.

Additionally, the organism will have characteristics that maximize the differential in gas concentration across the exchange surface.

A 2. 26 l balloon of helium is at 30°c and 1. 61 atm, what is the pressure if the volume is increased to 4. 12 l?.

Answers

Answer:

0.8832 atm

Explanation:

Per Boyle's Law:

If the temperature is held constant, the volume of a fixed amount of gas is inversely proportional to its pressure:

V∝[tex]\frac{1}{P}[/tex]

and

[tex]P_1V_1=P_2V_2[/tex]

To find pressure resulting from a change in volume:

[tex]\frac{P_1V_1}{V_2}=P_2[/tex]

So:

[tex]P_1=1.61atm\\V_1=2.26L\\V_2=4.12L\\P_2=\frac{(1.61atm)(2.26L)}{4.12L}\\P_2=0.8832atm[/tex]

This answer makes sense because Boyle's Law states that a given volume of gas at a constant temperature should have a proportionally lower pressure as the volume is increased.

the largest magnetic quantum number (m or ml) of an atom in the ground state is found to be 6. what must be the largest principal quantum number (n)?

Answers

The magnetic quantum number (m or ml) of an atom in the ground state is found to be 6. The largest principal quantum number of that atom is 4.

The magnetic quantum number(ml) of an atom determines the number of orbitals and the orientation present in the atom. To find out principal quantum number, first we need to find out the angular quantum number, which is l. It is calculated by the formula

m or ml=(2l+1)

The value of ml is 6. Plug the value in the formula

6=(2l+1)

2l=6-1

2l=5

l=5/2

If we round off this value to the nearest integer, then the value is 6/2 which is equal to 3.

When l=3, then the value of principal quantum number is calculated using the formula

l=n-1

Rearrange the formula for n and solve for n

n=l+1

n=3+1

n=4

Hence, the value of n is 4.

Therefore, the largest principal quantum number of the atom is 4.
