Draw the product formed when 2-butanol undergoes reaction with TsCl and Et3N. CH3C6H4SO2Cl.

Answer:

K = [Na2CO3] [H2O] [CO2] / [NaHCO3]²

Explanation:

2NaHCO3(s)⇋Na2CO3 (s) + H2O(g) + CO2(g)

To write an expression for equilibrium constant, K, for the above reaction, it is important that we have an idea of what equilibrium constant is all about and how we can determine it.

Equilibrium constant for a reaction is simply defined as the ratio of the concentration of the product raised to their coefficient to the concentration of the reactant raised to their coefficient.

Thus the expression for the equilibrium constant for the above equation can be written as follow:

K = [Na2CO3] [H2O] [CO2] / [NaHCO3]²

Answer:

This question appears to be incomplete

Explanation:

However, we know that one of the kinetic theories of gases is that gas molecules collide with one another and against the walls of the container (in which they are stored); hence exerting there pressure on the walls of this container.

Ideal gases are the most suitable for this theory because it's molecules are far apart and do not exert any attractive forces towards one another; hence it's molecules move "undisturbed" or "freely". For ideal gases, the average pressure exerted by by the gas molecules on the walls of the container can be calculated as

PV = nRT

Where P = pressure (in atmosphere, atm or kilopascal, KPa or millimeter mercury, mmHg)

V = volume (in liters)

n = number of molecules

R = ideal gas constant (8.3145 J·mol⁻¹·K⁻¹)

T = temperature (in kelvin)

Complete Question

Which is most reactive toward electrophilic aromatic substitution?

A  Phenol

B  Anisole

C  Nitro-benzene

D  Benzene

Answer:

The correct option is  A

Explanation:

Generally the rate at which electrophilic aromatic substitution reaction occur is dependent on the nucleophilicity(nucleophile strength  ) of Benzene ring.Now a functional group  which increase the electron density in the benzene ring when attached to it increases its  nucleophilicity and this in-turn will increase the rate at which electrophilic aromatic substitution reaction occur

Now   Phenol is a compound that is made up of  OH functional group and then the benzene ring

    Anisole is a compound that is made up of  [tex]OCH_3[/tex] functional group and then the benzene ring

    Nitro-benzene is a compound that is made up of  [tex]NO_2[/tex] functional group and then the benzene ring  

Now since OH is the highest In series of activating group compared to the activation groups we are considering (i.e  [tex]OCH_3[/tex]  and [tex]NO_2[/tex] )

Then  Phenol is the answer

Answer:

The flow rate of a tube is the volume of fluid flowing through the tube per unit time. The flowrate is proportional to the product of the velocity of the fluid through the tube, and the cross-sectional area of the tube.

That is

Q = AV

where

A is the area of the tube

V is the velocity of the tube

The cross-sectional area of the tube is proportional to the radius of the tube. From the above equation, we can deduce that if the velocity of the fluid flowing through the tube is held constant, the flowrate of the fluid through the tube will increase with an increase in the radius of the tube, and it will decrease with a decrease in the radius of the tube.

Answer:

Limestone caves are formed when acid rain occurs.

Explanation:

When chalk pieces which is made of calcium carbonate react with acetic acid, it produces carbon dioxide, calcium acetate, and water. When calcium carbonate react with Carbonated Water produces calcium bicarbonate. Limestone cave forms when the dissolution of limestone occur when rainwater which is acidic due to the addition of carbondioxide in the air react with limestone. This dissolution removes the lime from the rock and caves are formed.

The chalk has been made up of calcium carbonate. The reaction of calcium carbonate with different solutions results in the formation of varying products.

The reaction of chalk with acetic acid results in the formation of Calcium acetate, with the production of carbon dioxide and water.

The reaction of chalk with carbonated water results in the formation of calcium bicarbonate.

The limestone caves has been formed by the dissociation of limestone with reaction of acid, forming carbon dioxide.

The formation has takes place in the acidic solution, and carbon-dioxide thus the resultant can be due to the acid rain.

Answer:

750g of Aluminum

Assuming 8.6 cm lenth is the height of the cylinder. The volume of a cylinder is: V = [tex]\pi[/tex]*r^2*h

V = 3.14cm x 10.24cm x 3.6cm

V = 280cm^3

Now density = mass/volume

2.7g/cm^3 = mass/280cm^3

2.7g/cm^3 x 280cm^3 = mass/280cm^3 x 280cm^3

= 750g of Aluminum

Answer:

Solvent will be lost as gas and not return into the vessel via condensation.

Explanation:

Reflux is a technique used in chemistry to boil a particular solvent and convert the gas formed back into liquid by condensation. This technique allows a solvent to be heated at a regulated temperature but for a prolonged period of time than it would normally take place.

The reflux procedure makes use of a reflux CONDENSER, which is an apparatus that allows vapour from the heating/boiling to flow back into the reaction vessel. The CONDENSER functions to prevent the loss of the SOLVENT as vapour by providing a cooling effect on the vapour.

Therefore, if a reaction was refluxed without a condenser, THE SOLVENT WILL BE LOST AS VAPOUR

wdescribes the probability of finding an electron in space.

Explanation:

The quantum mechanical model of the atom assigns wave properties to the electron. This is in accordance with Heisenberg's uncertainty principle.

The probability of finding the electron in a given volume element is given as the square of the wave function while the wave function itself does not really have a physically significant meaning.

However, the wave function is a mathematical function that contains a detailed information about the behavior of an electron.

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question

mass of ice = 52.75 g

density = 0.917 g/cm³

The volume of the ice is

[tex]volume = \frac{52.75}{0.917} \\ = 57.52453653[/tex]

Answer:

Freezing T° of solution =  - 7.35 °C

Explanation:

This is about the freezing point depression, a colligative property which depends on solute.

The formula is: Freezing T° pure solvent - Freezing T° solution = m . Kf . i

Freezing T° of pure solvent is -3.1°C

At this case, i = 1. As an organic compound the urea does not ionize.

We determine the molality (mol/kg of solvent)

We convert mass to moles:

12.3 g . 1mol / 60.06 g = 0.205 moles

0.205 mol / 0.3 kg = 0.682 mol/kg

We replace data in the formula:

-3.1°C - Freezing T° of solution  = 0.682 mol/kg . 6.23 kg°C/mol . 1

Freezing T° of solution = 0.682 mol/kg . 6.23 kg°C/mol . 1 + 3.1°C

Freezing T° of solution =  - 7.35 °C

The nuclear magnetic resonance (NMR) spectroscopy is a method that employs the technique to observe the local magnetic fields are atoms. This analytical technique exploits sufficient differences in the frequency of nuclear magnetic resonance in protons and atoms within organic compounds that depend on their neighboring atoms.

Amongst all the given options, the carbonyl is the right option because the carbon is doubly bonded to the oxygen and the hybridization of this double bond is sp² hybridized, as a result, the electron density at the carbon possess a lower amount in order to have more magnetic field.
