Question
1) Given
C(s) + O2 (g) → CO2 (g) ΔH= +393.5 kJ
S(s) + O2 (g) → SO2 (g) ΔH= +296.8 kJ
What will be the ΔH for the following reaction?
SO2 (g) + C (s) + → CO2 (g) + S (s)
2) Given the following table of ΔHf values,
Compound ΔHf (kj/mol)
C2H5OH(l) = −277.6
H2O(l) = −285.8
H2O(g) = −241.8
CO2(g) = −393.5
CO(g) = −110.5
H2O2(l) = −187.6
C3H8(g) = −103.8
What is the ΔH for the reaction that forms C2H5OH(l) and oxygen gas by combining CO2(g) and
H2O(l)?
6) Which outer electrons experience a greater effective nuclear charge? He or H
