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.

<h3>What is magnetic force?</h3>Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion.The magnitude of the magnetic force acting on the charge is given by:
where
The magnitude of the charge
The velocity of the charge
The magnitude of the magnetic field
The angle between the directions of v and B
By substituting the values we will get:
Hence the magnitude of the force on the charge by the influence of the magnetic field will be 6.6*10^-3 N
