Given following electron configurations, 1s22s22p63s23p4s23d104p65s4d9 and 1s22s22p63s3p4s23d104p65s4d10 Part 1: Name the element
Part 2: Both electron configurations are correct, and the second one is what is found most often in nature. Suggest a reason for why silver most often exists as an exception to the normal electron configuration rules

Ci hope  it  you

That is a lot of moles that you have

Ithink its called the coefficent.

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 -
