Some "Beetles" Defend Themselves by Spraying Hot Quinone, C₆H₄O₂(l), at Their

Some "beetles" defend themselves by spraying hot quinone, C₆H₄O₂(l) , at their enemies. Calculate △H° for this reaction. C₆H₄(OH) ₂(l) + H₂O₂(l) → C₆H₄O₂(l) + 2H₂O(l)
Given: C₆H₄(OH) ₂(l) → C₆H₄O₂(l) + H₂(g) +177.4 kJ
The standard enthalpies of formation of H₂O₂(l) and H₂O(l) are -187.4 and -285.8 kJ/mol, respectively.

A) -206.8 kJ
B) -384.2 kJ
C) -561.6 kJ
D) +79.00 kJ
