Hydrogen burns exothermically in oxygen
Oliga [24]

Answer:

C. -486 kJ/mol

Explanation:

Enthalpy change equals bonds broken (reactants) minus bonds formed (products)

Bonds broken = 2 H-H bonds + 1 O=O double bond = 2(436) +498 = 1,370 kJ/mol

Bonds formed = 4 O-H bonds = 4(464) = 1,856 kJ/mol

Bonds broken - bonds formed = 1,370 - 1,856 = -486 kJ/mol
