Question

H2->HBr->H2O->Ca(OH)2->CaCl2->Ca->CaO->H2O​

Answer 1

Ответ:

Br2 + H2 →(t°) 2HBr

HBr (разб.)+ NaOH (разб.)→ NaBr + H2O

CaO + H2O → Ca(OH)2

Ca(OH)2 + 2HCl (разб.)→ CaCl2 + 2H2O

CaCl2 (расплав)→ Сa + Cl2↑ (электролиз)

2Ca + O2 →(t°) 2CaO

CaO + 2HNO3 → Ca(NO3)2 + H2O

Answer 2

The given sequence represents a series of chemical reactions. Let's break it down step by step:

1. H2 -> HBr: This reaction involves the conversion of hydrogen gas (H2) to hydrogen bromide (HBr). Unfortunately, I couldn't find any specific information about this reaction in the provided search results.

2. HBr -> H2O: This reaction involves the conversion of hydrogen bromide (HBr) to water (H2O). Again, I couldn't find any specific information about this reaction in the provided search results.

3. H2O -> Ca(OH)2: This reaction involves the conversion of water (H2O) to calcium hydroxide (Ca(OH)2). Unfortunately, I couldn't find any specific information about this reaction in the provided search results.

4. Ca(OH)2 -> CaCl2: This reaction involves the conversion of calcium hydroxide (Ca(OH)2) to calcium chloride (CaCl2). I couldn't find any specific information about this reaction in the provided search results.

5. CaCl2 -> Ca: This reaction involves the conversion of calcium chloride (CaCl2) to calcium (Ca). I couldn't find any specific information about this reaction in the provided search results.

6. Ca -> CaO: This reaction involves the conversion of calcium (Ca) to calcium oxide (CaO). I couldn't find any specific information about this reaction in the provided search results.

7. CaO -> H2O: This reaction involves the conversion of calcium oxide (CaO) to water (H2O). I couldn't find any specific information about this reaction in the provided search results.

Based on the search results, it seems that the specific reactions mentioned in the given sequence are not widely discussed or documented. It's possible that these reactions are not commonly studied or are specific to a particular context or experiment.

If you have any additional information or context about these reactions, I would be happy to try and provide a more detailed explanation.
