What is the molarity of a solution with 0.500 moles of CuSO4 dissolved to make 1.50 liters? a) 4.50 M
b) 2.0 M
c) 0.333 M
d) 0.250 M

Acovalent bond is formed between the two hydrogen bonds

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Ibelieve the answer is d. bleachhope my answer has you : )

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 -
