use the following reaction: N2(g) + 3H2(g) → 2NH3 (g). Delta H= -115K 2NH(g) +4H2(g) ->2NO2(g) +7H2 delta h= -142.5kj H2O(l)-> h2+1/2O2 deltaH=-43.7kJ determine DH of this reaction N2g+2O2g-> 2NO2g

Based on the following reactions: Rxn A: C{s) + O2(g) → CO2 (g) AH°C = -393.5 kJ/mole Rxn B: C3H18() + 25/2 O2lg) → 8CO2(g) + 9H2O) AH°C = -5461 kJ/mole Which reaction would produce more heat 10*A or B? 10*A would produce more heat B would produce more heat they would produce the same amount of heat

Please see attached photo and help solve for #8. Thanks!

14. Calculate the enthalpy change for the reaction below: C2H4 (g) + 6 F2 (g) → 2 CF4 (g) +4 HF (g) AH=??? based on the following reactions: H2 (g) + F2 (g) → 2 HF (g) AH= -537 kJ C (s) + 2 F2 (g) → CF4 (g) AH= -680 kJ 2 C (s) + 2 H2 (g) → C2H4 (g) AH=+52.3 kJ 15. Determine the enthalpy change for the reaction below: C (s) + H2O (g)- CO (g) +H2 (g) AH=??? based on the following reactions: C (s) + O2 (g) →CO2 (g) AH=-393.5 kJ 2 CO (g) + O2 (g) →2 CO2 (g) 2 H2 (g) + O2 (g) 2 H20 (g) AH=-566.0 kJ AH=-483.6 kJ
