Hydrogen gas and oxygen gas react to form water vapor. Suppose you have 1.0 mol of H, and 9.0 mol of O2 in a reactor. How much H2 will be left? Round your answer to the nearest 0.1 mol.

Wow that a lot of text for my tiny so i no wanna answer

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 -
