WebNov 4, 2024 · Remember, the heat of formation of H + is zero. The equation becomes: ΔH = ΔHf Br - (aq) - ΔHf HBr (g) The values for ΔHf may be found in the Heats of Formation of Compounds of Ions table. Plugging in these numbers: ΔH = -120.9 kJ - (-36.2 kJ) ΔH = -120.9 kJ + 36.2 kJ ΔH = -84.7 kJ Answer ΔH = -84.7 kJ WebWell, the heat that goes out from the reaction goes into the mixture. That is why the sign has to change here. We also need the temperature difference, which was measured to be Δ T = 3.38 K. The final result (the heat capacity) is calculated via q tot = m tot c tot Δ T ⇒ c tot = q tot m tot Δ T = 2.868 k J 200 g × 3.38 K = 4.243 J g − 1 K − 1
