Answer:
Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.
The equilibrium can be affected when there is a change of concentration, pressure or temperature of the system. Since it is mentioned that the temperature is constant, and the parameter being focused on is the initial amount, that should be the concentration factor. It depends where substance X is placed in the reaction. If it is a reactant (left side), then the equilibrium would shift and favor the forward reaction. If it is a product (right side), then the equilibrium would shift and favor the reverse reaction.
Answer:
Because of its permeability.
