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.

Given,

M=6.5kg,velocity(v)=6m/s

K.E=1/2mv^2

=1/2×6.5×6^2

=1/2×6.5×36

=18×6.5

=117 J

Why do animals need carbohydrates in their diets
Sever21 [200]

Answer:

Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.

In the experiment involving hydrated copper sulfate, overheating causes a high calculated percent value for water. why is the hi
Strike441 [17]
The answer to this question would be: Because the increase of temperature will increase volume.

Using PV=nRT formula we can see that temperature increase will cause an increase in volume. Overheating will cause the volume increase, then increasing the volume. If the percent value used is based on the volume, it will seem that the water is increased. But if the percent is using mass, there will be no increases.
That is why sometimes scientists using molality in a reaction with high temperature changes.
