SIMPLE ALGORITHM: Correct significant figures and rounding off (Conventional).

6. Given the following reactions:

CaCO3(s) → CaO(s) + CO2(g)                ΔH = 178.1 kJ

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

Determine the enthalpy of the reaction of CaCO3(s) → CaO(s) + C(s, graphite) + O2(g).
