What describes how the bond between two oxygen atoms is formed
HACTEHA [7]

The bond that exist between two oxygen atoms is called a double covalent bond. This bond involves the sharing of four electrons to obtain a more stable structure. This type of bond is much stronger than the single covalent bond. They are much harder to break.

568 cm3 of chlorine at 25° C will occupy what volume at -25° C while the pressure remains constant?
Vsevolod [243]

Answer:

474.3 cm³

Explanation:

Given data:

Initial volume of chlorine gas = 568 cm³

Initial temperature = 25°C

Final volume = ?

Final temperature =  -25°C

Solution:

Initial temperature = 25°C (25+273 = 297 K)

Final temperature =  -25°C (-25 +273 = 248 K)

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 568 cm³ × 248 K /297 K

V₂ = 140864 cm³.K / 297 K

V₂ = 474.3 cm³

Your teacher needs a 3.0M solution acid, but only has a 12.0M stock solution of sulfuric acid in the chemical store room. Calcul
arlik [135]

Answer:

The calculations are in the explanation below.

The <em>steps </em>are:

  • 1. Using a graduated pipette, accurately take 25mL of the 12.0M stock solution.
  • 2. Pour the 25mL of stock solution into a 100 mL volumetric flask
  • 3. Add distilled water up to the mark
  • 4. Cap the flask with the stopper
  • 5. Stirr by gently rotating the flask.

Explanation:

To make 100 mililiter of the 3.0M solution of sulfuric acid, first you must calculate the volume of the 12.0M stock solution that contains the same number of moles as the diluted solution.

For that, you use the dilution formula:

  • number of moles = C₁V₁ = C₂V2
  • 12.0M×V₁ = 3.0M × 100mL
  • V₁ = 3.0M × 100mL/12.0M = 25mL

Then, the steps are:

1. Using a graduated pipette, accurately take 25mL of the 12.0M stock solution.

2. Pour the 25mL of stock solution into a 100 mL volumetric flask

3. Add distilled water up to the mark

4. Cap the flask with the stopper

5. Stirr by gently rotating the flask.
