To draw a lewis structure for a polyatomic ion, begin by calculating a, the available electrons, and n, the needed electrons. what is n clo3 the chlorate ion?

You need to divided twenty four by a dozen them by the temperature it is getting cook by

Wow that a lot of text for my tiny so i no wanna answer

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 -
