How many atoms of Sn are in 0.796 moles of this element?

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.

Hello.the answer is  hydrosphere, geosphere, and biosphere  have a nice day

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 -
