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.

How there is a difference between the stick mass and the bug mass, we define that
Mass of the bug= m
Mass of the stick=10m
At the point 0 we have that,
Where l is the lenght of the stick which is also the perpendicular distance of the bug's velocity
vector from the point of reference (O), and ve is the velocity
At the end with the collition we have
Substituting
Applying conservative energy equation we have
Replacing the values and solving
Substituting
l=\frac{13}{0.54(9.8)}
