Which of the following statements is true of water in a solid state? Choose all that apply.

A. There are covalent bonds between each water molecule.
B. Solid water conforms to the shape of its container.
C. Water molecules in ice do not interact with each other very often.
D. It is rigid and forms a three-dimensional crystalline shape.
E. Water molecules in ice remain in a relatively fixed position and are not as mobile as they are in the liquid state, where there are fewer hydrogen bonds.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

it is stable as it is in group 0 which have full outer shells of electrons
