Calcium carbonate decomposes in this balanced equation: CaCO3 = CaO + CO2. ΔH = +110 kJ/mol A. Is this reaction endothermic or exothermic? B. If 45.3g of CaCO3 is decomposed, how much energy is released or absorbed
Added by Jennifer N.
Step 1
The reaction is endothermic because the enthalpy change (!H) is positive, which means energy is absorbed. B. Show more…
