3. Look at the periodic table listing ionic radii trends. Why are the radii changing as you move down the table within one column? Why are the radii changing as
you move across the table from left to right within one row?

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:

i have no clue hope you find the answer

if you're asking what comes out, it's steam.
