Use the standard heats of formation provided to choose the choice that show the valid math statement and math claim to calculate the standard heat of reaction for the reaction between hydrogen gas and oxygen gas shown.
2H2 (g) + O2 (g) → 2H2O (l)
Substance ΔH°f (kJ/mol)
H2 (g) 0
O2 (g) 0
H20 (l) -285.8
A)(0-0) - (-285) = 285 kJ/mol
B)0 - (-285-0) = -285 kJ/mol
C)-285 - (0-0) = -285 kJ/mol
D)(-285-0) - (0) = 285 kJ/mol
