An aqueous solution of hydroiodic acid is standardized by titration with a 0.185 M solution of calcium hydroxide. If 15.5 mL of base are required to neutralize 12.4 mL of the acid, what is the molarity of the hydroiodic acid solution?

The water cycle increase the water content in the earth atmosphere

It decreases by 4 is your answer mark brainliest 

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
