What is the enthalpy of formation of the substances given the change in enthalpy of reaction? Assign whether the process is endothermic or exothermic.

a.) Determine ΔH?_f for methanol (CH₃OH) given:

2CH₃OH (l) + 3O₂ (g) → 2CO₂ (g) + 4H₂O (g) ΔH? = -1199 kJ

b.) Determine ΔH?_f for glycine (C₂H₅NO₂) given:

4C₂H₅NO₂ (s) + 9O₂ (g) → 8CO₂ (g) + 10H₂O (l) + 2N₂ (g) which liberates 3896 kJ of heat under constant pressure.

c.) Determine ΔH?_f for formic acid (CH₂O₂) given:

HCHO₂ (l) → CO (g) + H₂O (l) which liberates 33kJ of heat under constant pressure.

d.) Determine ΔH?_f for baking soda (sodium bicarbonate) given:

2NaHCO₃ (s) → Na₂CO₃ (s) + H₂O (l) + CO₂ (g) which absorbs 85 kJ of heat under constant pressure.
