?Using values from Appendix C, calculate the value of \(\Delta H^{\circ}\) for each of

Chapter 5, Problem 5.74

(choose chapter or problem)

Using values from Appendix C, calculate the value of \(\Delta H^{\circ}\) for each of the following reactions:

(a) \(\mathrm{CaO}(s)+2 \mathrm{HCl}(g) \longrightarrow \mathrm{CaCl}_{2}(s)+\mathrm{H}_{2} \mathrm{O}(g)\)

(b) \(4 \mathrm{FeO}(s)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{Fe}_{2} \mathrm{O}_{3}(s)\)

(c) \(2 \mathrm{CuO}(s)+\mathrm{NO}(g) \longrightarrow \mathrm{Cu}_{2} \mathrm{O}(s)+\mathrm{NO}_{2}(g)\)

(d) \(4 \mathrm{NH}_{3}(g)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{~N}_{2} \mathrm{H}_{4}(g)+2 \mathrm{H}_{2} \mathrm{O}(l)\)

Text Transcription:

\Delta H^{\circ}

CaO(s) + 2 HCl(g) \longrightarrow CaCl21s2 + H2O(g)

4 FeO(s) + O2(g) \longrightarrow 2 Fe2O3(s)

2 CuO(s) + NO(g) \longrightarrow Cu2O(s) + NO2(g)

4 NH3(g) + O2(g) \longrightarrow 2 N2H4(g) + 2 H2O(l)
