2.50 L of a gas at standard temperature and pressure is compressed to 575 mL. What is the new pressure of the gas
vfiekz [6]

Answer:

4.35 atm

Explanation:

According to the information given;

  • Initial volume of the gas, V₁ is 2.50 L
  • Initial pressure of the gas is standard pressure P₁, normally 1 atm
  • New volume of the gas, V₂ is 575 mL

We are required to determine the new pressure of the gas, P₂ ;

To answer the question, we are going to use the Boyle's law, that relates pressure and volume at constant temperature.

According to Boyle's law;

P₁V₁ = P₂V₂

Therefore, to determine the new pressure, P₂, we rearrange the formula;

New pressure, P₂ = P₁V₁ ÷ V₂

Thus;

P₂ = ( 1 atm × 2.50 L) ÷ 0.575 L

    = 4.3478 atm

     = 4.35 atm

Therefore, the new pressure of the gas is 4.35 atm

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.

3. If a cation replaces an anion, the compound would have 2 positive charges. Why would this never happen
Jet001 [13]

A cation will not replace an anion in a compound because the two positively-charged ions will repel each other.

<h3>Ions</h3>

Ions are atoms or group of atoms possessing an electrical charge.

  • Positively-charged ions are known as cations.
  • Negatively-charged ions are known as anions.

<h3>Ionic compounds</h3>

Ionic compounds are compounds which are composed of oppositely charged ions held together by strong electrostatic forces of attraction between the oppositely charged ions.

  • From law of electrostatics, like charges repel and unlike charges attract.

If a cation replaces an anion, the compound would have two l positive charges which will repel each other.

Therefore, a cation will not replace an anion in a compound because the two positively-charged ions will repel each other.
