Here is an intro to the problem: Limestone stalactites and stalagmites are formed in caves by the following reaction: Ca2+(aq)+2HCO−3(aq)→CaCO3(s)+CO2(g)+H2O(l) If 1 mol of CaCO3 forms at 298 K under 1 atm pressure, the reaction performs 2.46 kJ of P−V work, pushing back the atmosphere as the gaseous CO2 forms.

When the limestone, CaCO₃, is placed in the water, carbon dioxide (CO₂) bubbles form. That is because calcium ions (Ca²+) react with carbonate ions in limestone (CO₃²-) to create calcium carbonate (CaCo3). The equation for this reaction is: 2 Ca + 2 CO 3 ↔ CaCO 3 + CO 2 ↑+ heat. Since more hydroxide ions are present than hydrogen ...

Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates). calcium carbonate calcium oxide + carbon dioxide.
