How many moles of o2(g) are needed to react completely with 670 l of ch4(g) at stp to produce co2(g) and h2o(g) according to the following reaction: ch4(g) + 2o2 > co2(g) + 2h2o(g)

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 -
