A 50 ml sample of a 1.00 M solution of CuSO4 is mixed with 50 ml of 2.00 M KOH in a calorimeter. The temperature of both solutions was 20.2 degrees celsius before mixing and 26.3 degrees celsius after mixing. The heat capacity of the calorimeter is 12.1 J/K. From this data calculate delta H for the process. Assume the specific heat and density of the solution after mixing are the same as those of pure water.

Answer:   d.  carbon dioxide.

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 -
