In the gaseous state, the molecules are spread very widely apart from one another and are free to move about. If placed in a container, the molecules will occupy the volume of the container and take its shape as well.
The molecules in the liquid state are closer than in the gaseous state and less free to move about. They are in layers that slide over one another, allowing the substance to flow. If placed in a container, the liquid water will take its shape but not the volume.
The molecules in the solid state are fixed in position, only able to vibrate about their fixed points. The structure formed is rigid, it does not flow and its shape and volume are fixed.

Explanation:
Hello! Your answer will be C. If you need an explanation let me know!
Answer No 1:
The chemical model that is flawed is:
4 C2 + S8 → 4 CS2
In this reaction, there are more number of carbon atoms in the reactants but lesser number of cabon atoms in the products. For a reaction to be balanced, there should be the same number of atoms in the reactants and products. Hence, option A does not represent a balanced equation.
<em>Answer No 2:</em>
The correct option is B) The model shows an unbalanced number of carbon atoms.
Consider the equation:
4 C2 + S8 → 4 CS2
In the reactants side of the equation, there are 8 atoms of carbon. In the products side there are only four carbon atoms. This shows that this equation in not balanced because of the carbon atoms.
The number of sulfur atoms remains same before the reaction and after the reaction. There are eight sulfur atoms in the reactants as well as products.
