The chloromethylated polystyrene resin used for Merrifield solid-phase peptide synthesis is prepared by treatment of polystyrene

with chloromethyl methyl ether and a Lewis acid catalyst. The reaction involves the following steps: Reaction of the ether with the Lewis acid to form cation 1; Electrophilic aromatic substitution to form resonance stabilized cation 2; Deprotonation yields aromatic ether 3; Protonation to form protonated ether 4; Displacement by chloride ion to form the final product. Write out the mechanism on a separate sheet of paper and then draw the structure of the resonance contributors of the resonance stabilized cation 2.

State the ideal gas law equations and tell what each term means
slavikrds [6]
<h3><u>Answer and explanation;</u></h3>

Ideal gas law is the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.

The ideal gas law is given by;

PV=nRT, where

P is the Pressure

V is the volume of the gas.

n is the number of moles

R is the gas constant  and

T is the temperature

Exactly 1.0 mol N2O4 is placed in an empty 1.0-L container and is allowed to reach equilibriumdescribed by the equation N2O4(g)↔
Vilka [71]

Answer : The correct option is, (C) 1.1

Solution :  Given,

Initial moles of N_2O_4 = 1.0 mole

Initial volume of solution = 1.0 L

First we have to calculate the concentration N_2O_4.

\text{Concentration of }N_2O_4=\frac{\text{Moles of }N_2O_4}{\text{Volume of solution}}

\text{Concentration of }N_2O_4=\frac{1.0moles}{1.0L}=1.0M

The given equilibrium reaction is,

                           N_2O_4(g)\rightleftharpoons 2NO_2(g)

Initially                      c                 0

At equilibrium   (c-c\alpha)           2c\alpha

The expression of K_c will be,

K_c=\frac{[NO_2]^2}{[N_2O_4]}

K_c=\frac{(2c\alpha)^2}{(c-c\alpha)}

where,

\alpha = degree of dissociation = 40 % = 0.4

Now put all the given values in the above expression, we get:

K_c=\frac{(2c\alpha)^2}{(c-c\alpha)}

K_c=\frac{(2\times 1\times 0.4)^2}{(1-1\times 0.4)}

K_c=1.066\aprrox 1.1

Therefore, the value of equilibrium constant for this reaction is, 1.1

The heat gained by the ice melted the ice and raised the temperature of the melted ice from its initial temperature to the final
liberstina [14]

Answer:

True

Explanation:

When ice is heated, the ice gains heat.

This heat gained by the ice is both used to break the intermolecular forces in ice to form water, as well as to raise the temperature of the water to it's final temperature.
