I need someone to show me how to solve thus problem, I think I have the right idea, but I may be plugging in something wrong. What is ΔS° at 298 K for the following reaction? Fe2O3(s)+ 3CO(g)→ 3CO2(g) + 2Fe(s) Substance ΔG°f(kJ/mol) ΔH°f(kJ/mol) Fe2O3(s). -741.0 -822.2 CO(g) -137.2 -110.5 CO2(g) -394.4 -393.5 Thanks
please help

A 145 g sample of copper metal at 100.0°C is placed into 250.0 g of water at 25.0°C in a calorimeter. When the system reaches thermal equilibrium, the temperature of the water in the calorimeter is 28.8°C. Assume the calorimeter is perfectly insulated. What is the specific heat capacity of...
