Balance the following redox reaction. Step 1. Determine the oxidation states of the species involved. The charges don't match yet so this is not a balanced equation. We can use each halfreaction to balance the charges. Notice that the Clions drop out, as they are spectator ions and do not participate in the actual redox reaction. Step 2.

Problem: 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 kJ of PV work, pushing back the atmosphere as the gaseous CO2 forms. At the same time, kJ of heat is absorbed from the environment.

The production of portland cement begins with the quarrying of limestone, CaCO 3. Huge crushers break the blasted limestone into small pieces. The crushed limestone is then mixed with clay (or shale), sand, and iron ore and ground together to form a homogeneous powder. However, this powder is microscopically heterogeneous.

1. Limestone thermally decomposes in rotary kiln and thermally decomposes to create quicklime (calcium oxide) and carbon dioxide. This is an endothermic reaction 2. Quicklime is then added with water to make slaked lime (calcium hydroxide). This is an exothermic reaction 3. Slaked lime dissolves in water to create limewater 4.
