They are all made from carbon
Answer:
There will be a critical shortage. -In garden, water plants early in the morning or in the evening.
The balanced combustion reaction for one mole of ethane will be
C2H6 + 3.5 O2 ---> 2CO2(g) + 3H2O (l)
Enthalpy of reaction of combustion = ∑ΔHf (products)- ∑ΔHf (reactant)
ΔHf = enthalpy of formation
The enthalpy of formation of oxygen = 0 as it is an element in its native state
ΔHf C2H6 = -83.820 kJ / mole
ΔHf H2O = -285.830 kJ / mole
ΔHf CO2 = -393.509 kJ / mole
ΔHrxn = [2 X ΔHf CO2 + 3 X ΔHf H2O] - [ΔHf C2H6]
ΔHrxn = [2 X (-393.509) + 3 (-285.830)] - [-83.820]
ΔHrxn = -1560.688 kJ / mole
