The mechanism will include

a) Slow step: rate determining step

In this step the leaving group (chloride ion) will leave the substrate and will form carbocation

b) Fast step:

The cation will be attacked by nucleophile and will give the substituted product

the mechanism is shown as :

Final product of the solvolysis of tert-butyl bromide in methanol is 2-methoxy-2-methylpropane.

Further Explanation:

Nucleophilic substitution reaction:

Nucleophilic substitution reaction is the chemical reaction where electron rich nucleophile replaces the leaving group from the substrate. Nucleophilic reactions are widely used in the conversion of one functional group to another.

Nucleophilic substitution reactions are two types:

1. The nucleophilic substitution reaction {{\text{S}}_{\text{N}}}1 is a two-step substitution reaction. In the first step, the removal of the leaving group takes place in order to form the carbocation intermediate. The second step involves the formation of the product by the attack of the incoming nucleophile on the carbocation intermediate.

2. Nucleophilic substitution reaction {{\text{S}}_{\text{N}}}2 is a single step substitution reaction in which electron-rich species substitute leaving group. The attack takes place from the backside of the electrophilic center thus an inversion of the configuration takes place.

The mechanism of solvolysis of tert-butyl bromide in methanol is {{\text{S}}_{\text{N}}}1  type (refer to the image attached), therefore

Step 1: Formation of carbocation intermediate from tert-butyl bromide after leaving of bromide ion.

Step 2: Then methanol act as the nucleophile and attack on the carbocation intermediate.

Step 3: The last step is deprotonation to produce the final product is 2-methoxy-2-methylpropane.

Answer : The volume of CO_2 will be, 514.11 ml

Explanation :

The balanced chemical reaction will be,

HCO_3^-+HCl\rightarrow Cl^-+H_2O+CO_2

First we have to calculate the  mass of HCO_3^- in tablet.

\text{Mass of }HCO_3^-\text{ in tablet}=32.5\% \times 3.79g=\frac{32.5}{100}\times 3.79g=1.23175g

Now we have to calculate the moles of HCO_3^-.

Molar mass of HCO_3^- = 1 + 12 + 3(16) = 61 g/mole

\text{Moles of }HCO_3^-=\frac{\text{Mass of }HCO_3^-}{\text{Molar mass of }HCO_3^-}=\frac{1.23175g}{61g/mole}=0.0202moles

Now we have to calculate the moles of CO_2.

From the balanced chemical reaction, we conclude that

As, 1 mole of HCO_3^- react to give 1 mole of CO_2

So, 0.0202 mole of HCO_3^- react to give 0.0202 mole of CO_2

The moles of CO_2 = 0.0202 mole

Now we have to calculate the volume of CO_2 by using ideal gas equation.

PV=nRT

where,

P = pressure of gas = 1.00 atm

V = volume of gas = ?

T = temperature of gas = 37^oC=273+37=310K

n = number of moles of gas = 0.0202 mole

R = gas constant = 0.0821 L.atm/mole.K

Now put all the given values in the ideal gas equation, we get :

(1.00atm)\times V=0.0202 mole\times (0.0821L.atm/mole.K)\times (310K)

V=0.51411L=514.11ml

Therefore, the volume of CO_2 will be, 514.11 ml

How many molecules are in 3 moles of potassium bromide (KBr)
sattari [20]

Answer:

Your strategy here will be to use the molar mass of potassium bromide,

KBr

, as a conversion factor to help you find the mass of three moles of this compound.

So, a compound's molar mass essentially tells you the mass of one mole of said compound. Now, let's assume that you only have a periodic table to work with here.

Potassium bromide is an ionic compound that is made up of potassium cations,

K

+

, and bromide anions,

Br

−

. Essentially, one formula unit of potassium bromide contains a potassium atom and a bromine atom.

Use the periodic table to find the molar masses of these two elements. You will find

For K:

M

M

=

39.0963 g mol

−

1

For Br:

M

M

=

79.904 g mol

To get the molar mass of one formula unit of potassium bromide, add the molar masses of the two elements

M

M KBr

=

39.0963 g mol

79.904 g mol

≈

119 g mol

So, if one mole of potassium bromide has a mas of

119 g

m it follows that three moles will have a mass of

You should round this off to one sig fig, since that is how many sig figs you have for the number of moles of potassium bromide, but I'll leave it rounded to two sig figs

If a helium filled ballon has a volume of 3.4l at 25°c and 1.18atm., what is its volume at STP?​
vladimir2022 [97]

Answer:

3.711 L

Explanation:

The formula you need to use is the following:

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\

3.4L / 298 K = V2 / 273 K

V2 = 3.711 L
