A sample of sulfur hexafluoride gas occupies a volume of 5.10 L at 198 ºC. Assuming that the pressure remains constant, what tem
Ludmilka [50]

Answer:

When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K

Explanation:

Step 1: Data given

A sample of sulfur hexafluoride gas occupies a volume of 5.10 L

Temperature = 198 °C = 471 K

The volume will be reduced to 2.50 L

Step 2 Calculate the new temperature via Charles' law

V1/T2 = V2/T2

⇒with V1 = the initial volume of sulfur hexafluoride gas = 5.10 L

⇒with T1 = the initial temperature of sulfur hexafluoride gas = 471 K

⇒with V2 = the reduced volume of the gas = 2.50 L

⇒with T2 = the new temperature = TO BE DETERMINED

5.10 L / 471 K = 2.50 L / T2

T2 = 2.50 L / (5.10 L / 471 K)

T2 = 230.9 K = -42.1

When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K

Which statement explains the relationship between the amount of energy it takes to break a bond and the amount of energy release
ad-work [718]

<em>The statement that gives the relationship between energy needed in breaking a bond and the one that is released after breakin</em>g is

The amount of energy it takes to break a bond is always less than the amount of energy released when the bond is formed.

  • Bond energy can be regarded as amount of energy that is required in  breaking a particular bond.

  • For a bond to be broken Energy will be  added and when a bond is broken there will be release of energy

  • Bond breaking can be regarded as endothermic process, it is regarded as endothermic  because there is a lot of energy required to be absorbed.

  • Where ever a bond is broken, there must be formation of another bond

  • Bond forming on the other hand can be regarded as exothermic process, since there is a release of  releases energy.

Therefore, more energy is required in breaking of bond compare to energy released after breaking of bond.
