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.
