What is the heat of reaction (?H°rxn) for the combustion ofacetone (C₃H₆O) given the followingthermochemical equations? (Answer should come out to be?H°rxn = ?1755 kJ)

1. 3 C(s) + 3 H₂(g) + ½ O₂(g) ?C₃H₆O(?) ?Hf° = ?285.0 kJ

2. C(s) + O₂(g) ? CO₂(g) ?Hf° = ?394.0 kJ

3. H₂(g) + ½ O₂(g) ? H₂O(?) ?Hf° = ?286.0 kJ
