Question

Calculate ΔH for the following reaction, CaO(s)  +  CO2(g)  →  CaCO3(s)

given the thermochemical equations below.

                  2 Ca(s)  +  O2(g)  →  2 CaO(s)                                            ΔH = -1270.2 kJ

                  C(s)  +  O2(g)  →  CO2(g)                                                      ΔH = -393.5 kJ

                  2 Ca(s)  +  2 C(s)  +  3 O2(g)  → 2 CaCO3(s)              ΔH = -2413.8  kJ

Group of answer choices

A.) -178.3 kJ 

B.) +350.2 kJ 

C.) -750.1 kJ 

D.) +2870.6 kJ
