1. A high surface tension and a high boiling point both indicate that there are strong attractive forces, or strong intermolecular forces, between the
molecules in the liquid. Which liquid in this lab has the weakest
intermolecular forces? Which has the strongest? Explain your answer.

Ibelieve it's celsius. hope this .

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 -
