Question

Ca->CaO->Ca(OH)2->CaCo3->CaCe2​

Answer 1

Ответ:

2Ca + O2 → 2CaO

CaO + H2O → Ca(OH)2

Ca(OH)2 + CO2 → CaCO3 + H2O

CaCO3 + 2HCl → CaCl2 + H2CO3

Answer 2

The sequence you've provided seems to describe a chemical transformation of calcium (Ca) through various compounds. However, there seems to be a mix of chemical formulas and some incorrect or unclear representations. Let's clarify and correct this sequence:

1. Ca (Calcium) reacts with oxygen to form CaO (Calcium Oxide).
2. CaO can react with water (H2O) to form Ca(OH)2 (Calcium Hydroxide).
3. Ca(OH)2 can react with carbon dioxide (CO2) to form CaCO3 (Calcium Carbonate).
4. There is a mistake in the last step. CaCe2 does not represent a common chemical compound. If you meant to refer to a specific compound, please provide the correct chemical formula, and I can explain the reaction or transformation involved.

So, the corrected sequence is:

Ca -> CaO -> Ca(OH)2 -> CaCO3

If you have a specific compound in mind for the last step, please provide the correct chemical formula, and I can help you further.
