Limestone stalactites and stalagmites are formed in caves by the following reaction: Ca2+(aq) + 2HCO3 (aq) → CaCO3(s) + CO2(g) + H2O(l) -> 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, 38.80 kJ of heat is absorbed from the environment.

Part A
Limestone stalactites and stalagmites are formed in caves by the
following reaction:
Ca2+ (aq) + 2HCO3(aq) → CaCO3(s) + CO2(g) + H2O(l)
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, 38.80 kJ of heat is absorbed
from the environment.
