I only need the answers please

Consider the following chemical reaction at equilibrium: CO(g)+H2O(g)CO2(g)+H2(g) If H2 is removed, how will Keq for the reaction change? Consider the following reaction at equilibrium: NH3(aq)+H2O(I)NH4+(aq)+OH(aq) If a drop of HCl is added, how will K(eq) change? Which of the following will decrease the concentration of A if the reaction below is at equilibrium? A(aq)+B(s)3C(aq)H
