Question

Ca-cao-ca(oh)2-caco3-ca (hco3)2

Answer 1

2Ca + O2 = 2CaO
CaO + H2O = Ca(OH)2
Ca(OH)2 + CO2 = CaCO3 + H2O
CaCO3 + CO2 + H2O = Ca(HCO3)2

Answer 2

Chemical Equation

The equation you provided is a chemical equation that represents a reaction involving several compounds. Let's break it down step by step:

Ca + Ca(OH)2 → CaCO3 + Ca(HCO3)2

Reactants:

The reactants in this equation are:

- Ca (Calcium) - Ca(OH)2 (Calcium hydroxide)

Products:

The products formed in this reaction are:

- CaCO3 (Calcium carbonate) - Ca(HCO3)2 (Calcium bicarbonate)

Balanced Equation:

To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

2Ca + 2Ca(OH)2 → CaCO3 + Ca(HCO3)2

Now, the equation is balanced.

Reaction Explanation:

In this reaction, calcium (Ca) reacts with calcium hydroxide (Ca(OH)2) to form calcium carbonate (CaCO3) and calcium bicarbonate (Ca(HCO3)2).

Calcium hydroxide is a strong base, and when it reacts with calcium, it forms calcium carbonate, which is a white solid. This reaction is known as a precipitation reaction, where a solid is formed from the reaction of two aqueous solutions.

Calcium bicarbonate, on the other hand, is formed as a result of the reaction between carbon dioxide (CO2) and water (H2O) with calcium carbonate. This reaction is known as carbonation and is commonly observed in the formation of stalactites and stalagmites in caves.

Overall Reaction:

The overall reaction can be summarized as follows:

Calcium + Calcium hydroxide → Calcium carbonate + Calcium bicarbonate

2Ca + 2Ca(OH)2 → CaCO3 + Ca(HCO3)2

I hope this explanation helps! Let me know if you have any further questions.
