a sportsman whose business is renting rowboats must buy a pair of new oars for each of his 60 boats. if the oars cost $200 per dozen pairs, how much does he pay for the oars? (Chemistry)

I'm not sure but i will try to find out

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 -
