The determination of iron in industrial waste stream is often carried out by reacting the water sample with o-phenanthroline to form a red-orange complex that absorbs at 510 nm.
Compute the value of ΔH ° if the combustion products are CO2 (g) and H2O (g). it isgiven that: CO 2 (g) = ΔHf ° - 393.5 kJmol-1; H 2 O (l) = ΔHf ° -285.8 kJmol-1; H 2 O (g) = ΔHf ° -241.8 kJmol -1.
You are given the following data. S(s) + 3/2 O2(g) → SO3(g) ΔH = -395.2 kJ 2 SO2(g) + O2(g) → 2 SO3(g) ΔH = -198.2 kJ Calculate ΔH
