Write with balanced chemical equations, What happens when a) The water containing calcium bicarbonate is heated?
b) The water containing magnesium bicarbonate is heated?
c) The water possessing permanent hardness is treated with washing soda?
d) The water possessing temporary hardness is treated with lime water?​

They are all solids.

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 -
