Answer 2

Chemical Reactions:

The given chemical reactions involve various compounds and elements. Let's break down each reaction and its products:

1. Ca + 2H2O = Ca(OH)2 + H2 - Calcium (Ca) reacts with water (H2O) to form calcium hydroxide (Ca(OH)2) and hydrogen gas (H2).

2. Ca(OH)2 + Na2CO3 = CaCO3 + 2NaOH [[1]](https://uchi.ru/otvety/questions/reshite-tsepochku-prevrascheniy-ca-ca-oh-2-caco3-cao-cacl2-ca-t-bao-ba-oh-2-ba-no3-2-nano) - Calcium hydroxide (Ca(OH)2) reacts with sodium carbonate (Na2CO3) to produce calcium carbonate (CaCO3) and sodium hydroxide (NaOH).

3. CaCO3 = CaO + CO2 - Calcium carbonate (CaCO3) decomposes into calcium oxide (CaO) and carbon dioxide (CO2).

4. CaO + 2HCl = CaCl2 + H2O - Calcium oxide (CaO) reacts with hydrochloric acid (HCl) to form calcium chloride (CaCl2) and water (H2O).

5. CaCl2 = Ca + Cl2 - Calcium chloride (CaCl2) decomposes into calcium (Ca) and chlorine gas (Cl2).

6. Ca(HCO3)2 + 2NaOH = CaCO3 + Na2CO3 + H2O - Calcium bicarbonate (Ca(HCO3)2) reacts with sodium hydroxide (NaOH) to produce calcium carbonate (CaCO3), sodium carbonate (Na2CO3), and water (H2O).

7. CaSO4 + Na2CO3 = CaCO3 + Na2SO4 [[2]](https://swsu.ru/sveden/files/MU_Ximiya_SRSNo_2.pdf) - Calcium sulfate (CaSO4) reacts with sodium carbonate (Na2CO3) to form calcium carbonate (CaCO3) and sodium sulfate (Na2SO4).

8. Ca(HCO3)2 + Ca(OH)2 = ? - The reaction between calcium bicarbonate (Ca(HCO3)2) and calcium hydroxide (Ca(OH)2) is not specified in the available search snippets.

9. Ca(HCO3)2 + Ca(OH)2 = ? [[4]](https://invat.blob.core.windows.net/manuals/9%20%D0%BA%D0%BB%D0%B0%D1%81%D1%81-ru-%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F-2016-.pdf) - The reaction between calcium bicarbonate (Ca(HCO3)2) and calcium hydroxide (Ca(OH)2) is not specified in the available search snippets.

10. Ca(OH)2 + CO2 = ? [[4]](https://invat.blob.core.windows.net/manuals/9%20%D0%BA%D0%BB%D0%B0%D1%81%D1%81-ru-%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F-2016-.pdf) - The reaction between calcium hydroxide (Ca(OH)2) and carbon dioxide (CO2) is not specified in the available search snippets.

11. CaCl2 + Ca(OCl)2 + 2H2O = ? [[3]](https://rsr-olymp.ru/upload/files/tasks/350/2018/14287927-tasksans-chem-10-11-final-18-19.pdf) - The reaction between calcium chloride (CaCl2), calcium hypochlorite (Ca(OCl)2), and water (H2O) is not specified in the available search snippets.

12. Ca(HCO3)2 + Ca(OH)2 = ? [[4]](https://invat.blob.core.windows.net/manuals/9%20%D0%BA%D0%BB%D0%B0%D1%81%D1%81-ru-%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F-2016-.pdf) - The reaction between calcium bicarbonate (Ca(HCO3)2) and calcium hydroxide (Ca(OH)2) is not specified in the available search snippets.
