Show the calculation of the amount of heat involved if 35.6 g of H2S is reacted with excess O2 to yield sulfur dioxide and water by the following reaction equation. Report your answer to 4 significant figures. 2 H2S (g) + 3 O2 (g) → 2 SO2 (g) + 2 H2O (g) ΔH = - 1124 kJ Your Answer: 1) 1 mol H2S = 34.1 g of H2S = 603.2 KJ (35.6 g / 34.1 g) * -603.2 KJ = (1.0439) * (-603.2 KJ) = -629.7 2H2S (g) + 3 O2 (g) --> 2 SO2 (g) + 2 H2O (g) H = -1124 KJ reaction uses 35.6 g of H2S = 35.6 /...
