Answer:
The correct answer is: <em>The addition of water will change the concentration of the substances in equilibrium.</em>
Explanation:
For chemical reactions, the equilibrium constant is defined as the ratio between the concentration of products and reactants. In this expression pure substances should not be written, like pure liquids and gases. Since water is a pure liquid should not appear in the equilibrium. However, water is the solvent of all the solutes or substances in the reaction, thus the addition of water will make all the substances to be diluted. Also, because of the Le Châtelier principle the equilibrium should be re-establish and the concentrations whitten in the equilibrium constant should change too.
Scene B depicts chemical change in matter at atomic change.
Composition distinguishes a chemical reaction from a physical reaction. In a chemical process, the makeup of the components changes; in a physical change, the appearance, smell, or straightforward exhibition of a sample of matter changes without changing its composition. Despite the fact that we refer to them as physical "reactions," nothing is actually changing. A change in the substance in question's elemental composition is necessary for a reaction to occur. Therefore, from now on, we will simply refer to bodily "reactions" as physical changes.
