Given the data, ΔH0f [CO2(g)] = -378 kJ/mol ΔH0f [SrO(s)] = -600 kJ/mol ΔH0f [C(g)] = 730 kJ/mol

[answerhappygod]

Given the data,
ΔH0f [CO2(g)]
= -378 kJ/mol

ΔH0f [SrO(s)]
= -600 kJ/mol
ΔH0f [C(g)] = 730
kJ/mol

ΔH0f [O(g)]
= 269 kJ/mol
ΔH0 [SrO(s) +
CO2(g) → SrCO3(s)] = -230
kJ/mol
i) Calculate the average C=O bond energy (enthalpy) in
CO2.
ii)
Calculate ΔH0f [SrCO3(s)].
iii) Taking the result from i) as an approximation for the C=O
bond energy (enthalpy) in CO(g),
calculated ΔH0f [CO(g)]

I am so confused about this homework question, please help!
