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.

Your answer is the element of S I think.
We calculate the molar concentration [Cl⁻] using stoichiometry. MnCl2(aq) is an ionic compound which will have the releasing of 2 Cl⁻ ions ions in water for every molecule of MnCl2 that dissolves.
MnCl2(s) --> Mn+(aq) + 2 Cl⁻(aq)
[Cl⁻] = 0.68 mol MnCl2/1L × 2 mol Cl⁻ / 1 mol MnCl2 = 1.4 M
The answer to this question is [Cl⁻] = 1.4 M
Answer: The number of moles of 
produced are, 0.287 moles.
Explanation : Given,
Mass of 
= 14.9 g
Molar mass of = 32 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 13 mole of react to give 8 moles of
So, 0.466 mole of react to give 
mole of
Therefore, the number of moles of produced are, 0.287 moles.
