Question

Using the equations 2Sr(s)+O2(g) → 2 SrO (s) ΔH° = -1184 kJ/mol


Using the equations 

2Sr(s)+O2(g) → 2 SrO (s) ΔH° = -1184 kJ/mol 

SrO (s) +CO2 (g) → SrCO3 (s) ΔH° = -234 kJ/mol 

CO2 (g) → C(s) +O2 (g) ΔH°= 394 kJ/mol

 Determine the enthalpy for the reaction 

2 SrCO3 (s) → 2 Sr (s)+2 C(s)+ 3O2 (g). kJ/mol
