Question: Using the data in Appendix 3, calculate the standard entropy changes for the following reactions at 25C: (a) H2(g) + CuO(s) Cu(s) + H2O(g)

Using the data in Appendix 3, calculate the standard entropy changes for the following reactions at 25°C:
(a) H2(g) + CuO(s) → Cu(s) + H2O(g)
(b) 2Al(s) + 3ZnO(s) → Al2O3(s) + 3Zn(s)
(c) CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
