The equation for the reaction between lithium and water is 2Li(s) + 2H2O(l) o 2LiOH(aq) + H2(g)
(i) A mass of 0.500 g of lithium reacts with an excess of water.
Calculate the volume, in cm3
, of hydrogen gas produced at rtp.
[molar volume of a gas at rtp = 24 000 cm3
]
Give your answer to three significant figures.

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 -
