Determine the standard enthalpy change for the precipitation reaction of 10.0 g of calcium chloride (CaCl2) with excess sodium carbonate (Na2CO3) to form calcium carbonate (CaCO3) and sodium chloride (NaCl). Given the following standard enthalpies of formation: ΔHf°(CaCl2) = -795.8 kJ/mol, ΔHf°(Na2CO3) = -1130.1 kJ/mol, ΔHf°(CaCO3) = -1206.9 kJ/mol, and ΔHf°(NaCl) = -411.2 kJ/mol.

Consider the following chemical equation: 2 SO2(g) + O2(g) ⇌ 2 SO3(g)At equilibrium, the concentration of SO2 was found to be 0.10 M, the concentration of O2 was found to be 0.20 M, and the concentration of SO3 was found to be 0.30 M. What is the value of the equilibrium constant (Kc) for this reaction at the given temperature?
