Models of atoms and compounds help in understanding of concepts of reactions in chemistry.
<h3>What are models?</h3>
Models are objects used to provide a visual representation of certain things or structures.
Models are widely employed in chemistry because of their usefulness in strengthening understanding of concepts.
The importance of models in chemistry include:
- they help students to be able to visualize the structures of atoms and compounds in a macroscopic scale
- they provide an a clearer understand of how atoms combine to form products in reactions.
Therefore, models help in understanding of concepts of reactions in chemistry.

Answer: The staircase is 14.28 m high.
Explanation:
Given : Mass = 0.1 kg
Potential energy = 14 J
Potential energy is the energy occupied by the position of a substance. Therefore, formula for potential energy is as follows.
P.E = mgh
where,
m = mass
g = gravitational energy = 
h = height of object
Substitute the values into above formula as follows.
Thus, we can conclude that the staircase is 14.28 m high.
