3 P Question 41 Consider these reactions: Reaction 1: H2 (g) + Cl2 (9) 2HCI(g) AH = -184.6 kJ Reaction 2: 20F2(9) → 02 (9) + 2 F2(9) AH = -49.4 kJ Reaction 3: N2 (g) + 202(g) → 2NO2(g) AH = +66.4 kJ Use Reaction 1. Determine the mass, in grams, of chlorine gas consumed (with excess H2) when 1,721.0 kJ of energy is released from the system. Answer: g (mass must be positive; round to nearest whole number)
