Question

Ca(OH)2-CaCO3–CO2-CO-CO2

Answer 1

Ответ:

Объяснение:

Ca(OH)2 + CO2 = CaCO3 + H2O

CaCO3 + 2HCl = CaCl2 + CO2 + H2O

CO2 + C = 2CO

2CO + O2 = 2CO2

Answer 2

The chemical equation you provided seems to represent a series of reactions involving calcium hydroxide (Ca(OH)2), calcium carbonate (CaCO3), carbon dioxide (CO2), and carbon monoxide (CO). Here's a breakdown of the reactions:

1. Ca(OH)2 (calcium hydroxide) reacts with CO2 (carbon dioxide) to form CaCO3 (calcium carbonate) and H2O (water). This is known as a precipitation reaction, and the balanced equation is: Ca(OH)2 + CO2 → CaCO3 + H2O

2. CaCO3 (calcium carbonate) decomposes when heated, producing CO2 (carbon dioxide) and CaO (calcium oxide). The balanced equation is: CaCO3 → CaO + CO2

3. CO2 (carbon dioxide) can react with carbon (C) to produce carbon monoxide (CO). This is known as a carbonation reaction, and the balanced equation is: CO2 + C → 2CO

Overall, the sequence of reactions can be summarized as follows: Ca(OH)2 + CO2 → CaCO3 + H2O (Precipitation reaction) CaCO3 → CaO + CO2 (Decomposition reaction) CO2 + C → 2CO (Carbonation reaction)
