which statement describes the way in which energy moves between a system of reacting substances and surroundings ​
V125BC [204]

The complete question is as follows: Which statement describes the way in which energy moves between a system reacting substances in the surroundings.

A) molecule Collisions transfer thermal energy between the system and its surroundings

B) The thermal energy of the system and it’s surroundings increase

C) The potential energy of the system and it’s surroundings increases

D) molecular collisions create energy that is then released into the surroundings

Answer: The statement, molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.

Explanation:

When there will occur an increase in kinetic energy of molecules then there will occur more number of collisions.

When kinetic energy between these molecules tends to decrease then they will release heat energy into their surroundings.

As a result, it means that molecule collisions transfer thermal energy between the system and its surroundings.

Thus, we can conclude that the statement molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.

The electronegativity of nitrogen (n) is 3.0, while the electronegativity of hydrogen (h) is 2.1. knowing this, consider how the
Goryan [66]

The electronegativity of nitrogen (N) is 3.0, while the electronegativity of hydrogen (H) is 2.1. As it can be seen that nitrogen (N) is more electronegative than that of hydrogen (H),  

So electron pairs are attracted towards nitrogen and thus it carries a partial negative charge and hydrogen carries a partial positive charge. The image of electron distribution is attached as follows.

Thus NH₃ is a polar molecule .
