When 130. mL of 0.198 M NaCl(aq) and 130. mL of 0.198 M AgNO3(aq), both at 21.8°C, are mixed in a coffee cup calorimeter, the temperature of the mixture increases to 24.2°C as solid AgCl forms. NaCl(aq) + AgNO3(aq) → AgCl(s) + NaNO3(aq) This precipitation reaction produces 2.60 ✕ 103 J of heat, assuming no heat is absorbed by the calorimeter, no heat is exchanged between the calorimeter and its surroundings, and that the specific heat and density of the solutions are the same as those for water (4.18 J/g·°C, and 0.997 g/mL, respectively). Using this data, calculate ΔH in kJ/mol of AgNO3(aq) for the given reaction. This is the complete question, nothing was left out. Thank you

2. The predominant forms of heavy metals (Zn, Pb, Fe, Cu, Ni, etc.) in aerobic sediments are the carbonates and the oxide or hydroxide forms. An important consideration in modeling the sediment is the stable chemical form of the metal in question. Consider the reaction: AG = 25 kJ/mol Pb(OH)₂ (s) + CO₂(aq) → PbCO₂ (s) + H₂O a. At what partial pressure of CO₂(g) will Pb(OH)2(s) and PbCO3(s) be at equilibrium? b. If the system is at equilibrium with the atmosphere, Pc02-10-3.38 atm, calculate 4G for the reaction.
