How much heat energy is required to raise the temperature of 0.367 kg of copper from 23.0 ∘c to 60.0 ∘c? the specific heat of copper is 0.0920 cal/(g⋅∘c

The answer is d- principle of faunal succession.

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 -
