When hydrogen chloride reacts with sodium sulfide to form hydrogen sulfide gas and sodium chloride, the reaction is as
follows:
2HCl (aq) + Na2S (aq) --> H2S (g) + 2NaCl
What volume of hydrogen sulfide gas will be collected if
39.0 grams of sodium sulfide are reacted?

The think of process to make something successful

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 -
