Write a hypothesis for Part I of the lab, which is about the effect of mass on the ability of an object to absorb or release thermal energy. Use the format of "if . . . then . . . because . . .” and be sure to answer this part of the lesson question: "How does mass affect thermal energy transfer

The se-ci  bonds is more polar  than s-br bond

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 -
