The enthalpy change for the dissolution of sulphuric acid in water is -75.0kJ/mol. Concentrated sulphuric acid is an 18.1M solution. Calculate how much the temperature of the solution would change if you were making 1.38L of pH -0.56 H2SO4. Assume the solution has the same heat of solution as water, 4.186 kJ/Kg °C and the density of concentrated H2SO4 is 1.840 kg/L. Only your final answer is required to three sig figs.

A typical coal-fired electric generating plant will burn about 3 metric tons of coal per hour. Most of the coal burned in the United States contains 1 to 4 % by weight sulfur in the form of pyrite, which is oxidized as the coal burns: 4FeS2(s) + 11 O₂(g) 2 Fe2O3(s) + 8 SO2(9) Once in the atmosphere, the SO2 is oxidized to SO3, which then reacts with water in the atmosphere to form sulfuric acid: SO3(9) + H₂O(1)→→→→→→→ H₂SO4(aq) If 42.4 metric tons of coal that contains 1.44 % by weight S is burned and all of the sulfuric acid that is formed rains down into a pond of dimensions 397 m x 256 m x 4.96 m, what is the pH of the pond? (OK to assume 2 mol H30+ per mole H₂SO4.) Hint: 1 metric ton = 1000 kg
