A compound is composed of two elements and has the formula X2Y3. The molar mass of X is 26.98 g/mol and 1.1009 mol of the compound contains 165.32 g. What is the most likely identity of compound X2Y3, by formula and name?

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 -
