demonstrate that the change in enthalpy for a reaction, AH, is an extensive property. Using this property,calculate the change in enthalpy for Reaction 2.
Reaction 1: C3H8(g) +502 (g)-3CO2(g) + 4H₂O(g), AH₁ = -2043 kJ
Reaction 2: 4C3H8(g) +2002 (g)→12CO2(g) + 16H₂O(g), AH₂ =?
Express your answer to four significant figures and include the appropriate units.
