Consider a zinc-copper electrochemical cell in which the half-reaction Zn(s) → Zn²⁺(aq) + 2e⁻ occurs at the anode and the half-reaction Cu²⁺(aq) + 2e⁻ → Cu(s) occurs at the cathode. If the concentration of Zn²⁺(aq) in the anode compartment is 0.500 M and the concentration of Cu²⁺(aq) in the cathode compartment is 0.0250 M, calculate the current density when a current of 2.50 A is passed through the cell. (Assume that the temperature and pressure are constant and that the electrodes are inert.)

Calculate the standard enthalpy change (ΔH°) for the reaction where 1 mol of solid sodium hydroxide (NaOH) dissolves in excess water to produce 1 mol of aqueous solution and releases heat. Given that the standard enthalpy of formation (ΔH°f) for NaOH(s) is -425.6 kJ/mol, the heat capacity of the aqueous solution is 4.18 J/gK, and the change in temperature (ΔT) is observed to be 8.0°C for 250 g of the solution.

A chemistry student needs to determine the effect of adding NaCl to a solution containing AgNO3 at equilibrium. The original solution had concentration [Ag+]=0.01M and [NO3-]=0.01M, and Ksp=1.8x10^-10. How much NaCl (in grams) is needed to be added to the solution in order to decrease the [Ag+] concentration by a factor of 10?
