Problem- click the deltah is an extensive property button, Ask an Expert

Academics

Problem- Click the DeltaH is an Extensive Property button within the activity, and analyze the relationship between the two reactions that are displayed. The reaction that was on the screen when you started and its derivative demonstrate that the change in enthalpy for a reaction, ?H, is an extensive property. Using this property, calculate the change in enthalpy for Reaction 2.

Reaction 1: C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(l). ?Hº = -2220. kJ.

Reaction 2: 3C3H8(g)+15O2(g)→9CO2(g)+12H2O(g), ΔH2=? Find H2

Thank you! My final is tomorrow and I am in desperate need!
