Question

С —> СO2 —> СаСO3 —> СаСl2 —> Са(ОН)2;

Answer 1

Ответ:

Объяснение:

C + O2 = CO2

CO2 + Ca(OH)2 = CaCO3↓ + H2O

CaCO3 + 2HCl = CaCl2 + CO2↑ + H2O

CaCl2 + 2NaOH = Ca(OH)2 + 2NaCl

Answer 2

It looks like you've provided a sequence of chemical reactions involving carbon (C), carbon dioxide (CO2), calcium carbonate (CaCO3), calcium chloride (CaCl2), and calcium hydroxide (Ca(OH)2). Let's break down the reactions:

1. C → CO2:

   • This is the combustion of carbon (C) to form carbon dioxide (CO2).

2. CO2 → CaCO3:

   • This represents the absorption of carbon dioxide by calcium carbonate, resulting in the formation of calcium carbonate (CaCO3).

3. CaCO3 → CaCl2:

   • This could be a reaction where calcium carbonate reacts with hydrochloric acid (HCl) to form calcium chloride (CaCl2), carbon dioxide (CO2), and water (H2O).

4. CaCl2 → Ca(OH)2:

   • This reaction might involve the reaction of calcium chloride with sodium hydroxide (NaOH) or another hydroxide source to form calcium hydroxide (Ca(OH)2) and sodium chloride (NaCl).

If you have specific questions about these reactions or if you would like more information on any particular step, feel free to ask!
