A substance did not change its chemical nature in a reaction. Which most likely describes the reaction?
2 answers:
Answer: Option (D) is the correct answer.
Explanation:
- A reaction in which there occurs no change in chemical composition of a substance is known as a physical change or physical reaction.
For example, freezing of water is a physical change because only change in state is taking place.
A physical change never leads to the formation of a new substance.
- On the other hand, a change which brings change in chemical composition of a substance is known as a chemical change.
For example,
A chemical change will always lead to the formation of a new compound.
Thus, we can conclude that it was frozen most likely describes the reaction.

Answer:
Value of electric field along the axis and equitorial axis and
respectively.
Explanation:
Given :
Distance between charges ,
Magnitude of charges ,
Dipole moment ,
Case A) (x,y) = (12.0 cm, 0 cm) :
Electric field of dipole in its axis ,
Putting all values and
We get ,
Case B) (x,y) = (0 cm, 12.0 cm) :
Electric field of dipole on equitorial axis ,
Putting all values and
We get ,
Hence , this is the required solution.
