Question

Question 3 1 pts Gaseous ammonia reacts with oxygen to produce nitrogen and water vapor according to the following thermochemicl equation: 4 NH3(g) + 3029 +2 N2(g) + 6 H20 (g); AH = -1232 kJ How much heat (kJ) is produced when 17.9 g of ammonia are reacted in excess oxygen? (3 sig figs, fill in the number ONLY!) Question 4 0.5 pts Which of the following are intensive properties? Note that there may be more than one correct choice. Select all that apply. Entropy Temperature Mass Gibbs Energy Molar Enthapy, kJ/mol

Answer 1

4NH + 302 N₂ + 6H₂O (g) (g) (9) (9) OH = -1232 KJ 4 moles of NH on reaction gives - 1232 kJ 17.9 gm of NH will give x K) 17.9 X-1232 = -324 KJ 4817 & significant figiene 6 6 Intensive property It does not depend on the amoent of substance. Єy to op9. > extenie Вирол Temperature - Intensive property. Mass → extensive property Gibbs energy extensive property. Molar enthalpy. Intensive property. C
