To break a chemical bond, particles need to collide with a certain amount of

Explanation:

To break a chemical bond, it is required that particles must have certain amount of energy so that when they can collide with each other due to this energy.

Therefore, there will exist a certain amount of force between the particles which will help in breaking the chemical bond.

This energy due to the motion of particles is known as kinetic energy.

Thus, we can conclude that to break a chemical bond, particles need to collide with a certain amount of kinetic energy.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer to this question is 3.
