On the basis of your knowledge of the reaction of halogens with alkanes, decide which product you would not expect to be formed

KIM [24]

Answer:

On the basis of your knowledge of the reaction of halogens with alkanes, decide which product you would not expect to be formed in even small quantities in the bromination of ethane?

A) BrCH2CH2Br

B) CH3CH2CH2Br

C) CH3CHBr2

D) CH3CH2CH2CH3

E) BrCH2CH2CH2CH2Br

Explanation:

The reaction of ethane with bromine in presence of UV light forms mono substituted ethane at all primary and secondary carbons.

This is an example of free radical substitution.

The structure of ethane and its bromination is shown below:

Among the given options that which is not possible to form is option B) that is CH3CH2CH2Br(propyl bromide).

Remaining all other products are possisble to form on free radical substitution of ethane.

Mass of oxygen produced from 0.02 moles

faust18 [17]

Answer:

0.64 g O₂

Explanation:

I am assuming you meant 0.02 moles of O₂. In that case, convert moles to mass via stoichiometry:

0.02 mol O₂ x 32 g O₂/1 mol O₂ = 0.64 g O₂

If 6 moles of A and 2 moles of B are reacted, what is the maximum number of moles of C that can be formed

MaRussiya [10]

The question is incomplete, here is the complete question:

Suppose the reaction is:

$A+2B\rightarrow C$

If 6 moles of A and 2 moles of B are reacted, what is the maximum number of moles of C that can be formed

<u>Answer:</u> The maximum amount of C produced will be 1 mole

<u>Explanation:</u>

We are given:

Moles of A = 6 moles

Moles of B = 2 moles

For the given chemical reaction:

$A+2B\rightarrow C$

By Stoichiometry of the reaction:

2 moles of B reacts with 1 mole of A

So, 2 moles of B will react with = $\frac{1}{2}\times 2=1$ mole of A

As, As, given amount of A is more than the required amount. So, it is considered as an excess reagent.

Thus, B is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

2 moles of B produces 1 mole of C

So, 2 moles of given B will produce $=\frac{1}{2}\times 2=1mol$ of C

Hence, the maximum amount of C produced will be 1 mole

Calculate the average reaction rate of Cl2 consumed using the following information. H2 + Cl2 yields 2 HCl A table with three co

klemol [59]

Answer : Option D) 2.50 X $10^{-3}$ Mol/(L s)

Explanation: While calculating the average reaction rate for the given reaction in terms of Cl;

$H_{2} + Cl_{2} ----\ \textgreater \ 2HCl$ .

using the rate equation which is;

$\frac{-1}{1}$ $\frac{delta [Cl]}{delta t}$ =

$\frac{- 0.0875 - 0.0625}{10s - 0s}$ = 2.50 X $10^{-3}$ Mol/(L s)

What does lower case k stand for?

DaniilM [7]

Just for more clarification, lowercase k is the rate constant. Uppercase K is the equilibrium constant. You can actually use k to find K (equilibrium constant). K=k/k' This means that the equilibrium constant is the rate constant of the forward reaction divided by the rate constant of the reverse reaction
