Question

Здійсніть перетворення C - CO2 - CaCo3 - CaCl2 - Ca(OH)2​

Answer 1

1) C+O2 → CO2

2) CO2+CaO → CaCo3

3)2 NaCl  + CaCO3  → Na2CO3 + CaCl2

4)СаCl2 + 2Н2О → Са(ОН)2 + 2НCL

Answer 2

Transformation of C to CO2

To transform C (carbon) into CO2 (carbon dioxide), you need to combine carbon with oxygen. The balanced chemical equation for this reaction is:

C + O2 → CO2

In this equation, one molecule of carbon reacts with one molecule of oxygen gas to produce one molecule of carbon dioxide.

Transformation of CO2 to CaCO3

To transform CO2 (carbon dioxide) into CaCO3 (calcium carbonate), you need to combine carbon dioxide with calcium ions. The balanced chemical equation for this reaction is:

CO2 + Ca(OH)2 → CaCO3 + H2O

In this equation, one molecule of carbon dioxide reacts with one molecule of calcium hydroxide to produce one molecule of calcium carbonate and one molecule of water.

Transformation of CaCO3 to CaCl2

To transform CaCO3 (calcium carbonate) into CaCl2 (calcium chloride), you need to replace the carbonate ion with chloride ions. The balanced chemical equation for this reaction is:

CaCO3 + 2 HCl → CaCl2 + H2O + CO2

In this equation, one molecule of calcium carbonate reacts with two molecules of hydrochloric acid to produce one molecule of calcium chloride, one molecule of water, and one molecule of carbon dioxide.

Transformation of CaCl2 to Ca(OH)2

To transform CaCl2 (calcium chloride) into Ca(OH)2 (calcium hydroxide), you need to replace the chloride ions with hydroxide ions. The balanced chemical equation for this reaction is:

CaCl2 + 2 NaOH → Ca(OH)2 + 2 NaCl

In this equation, one molecule of calcium chloride reacts with two molecules of sodium hydroxide to produce one molecule of calcium hydroxide and two molecules of sodium chloride.

Please note that these transformations involve chemical reactions and may require specific conditions such as temperature, pressure, or the presence of a catalyst.
