Question

What is the value of Change in H for this reaction?

what is the change in E?

Limestone stalactites and stalagmites are formed in caves by the following reaction: 2+ Ca²+ (aq) + 2HCO3(aq) → CaCO3 (s) + CO₂(g) + H₂O(1) If 1 mol of CaCO3 forms at 298 K under 1 atm pressure, the reaction performs 2.45 kJ of P-V work, pushing back the atmosphere as the gaseous CO₂ forms. At the same time, 38.65 kJ of heat is absorbed from the environment.
