Answer 1

(C6H12O5)n + nH2O -> nC6H12O6
C6H12O6 -> 2С2H5OH + 2CO2↑
C2H5OH [O]-> CH3CHO + H2O
CH3CHO [O]-> CH3COOH
2CH3COOH + Nа2СО3 → 2CH3COONа + СО2↑ + H2О

Answer 2

Ответ:

Объяснение:

крохмаль → глюкоза → етанол → етаналь → етанова кислота → натрій етаноат

(C6H12O5)n + nH2O -> nC6H12O6

C6H12O6 -> 2С2H5OH + 2CO2↑

C2H5OH  [O]-> CH3CHO + H2O

CH3CHO  [O]-> CH3COOH

2CH3COOH + Nа2СО3 → 2CH3COONа + СО2↑ + H2О

Answer 3

Chemical Equations for the Given Scheme

The given scheme involves the conversion of starch to various compounds. Let's break down the scheme step by step and write the chemical equations for each conversion:

1. Starch to Glucose: - Starch is a polysaccharide composed of glucose units. - The conversion of starch to glucose can be represented by the following equation: ``` Starch → Glucose ```

2. Glucose to Ethanol: - Glucose is a monosaccharide that can undergo fermentation to produce ethanol. - The conversion of glucose to ethanol can be represented by the following equation: ``` Glucose → Ethanol + Carbon Dioxide ```

3. Ethanol to Ethanal: - Ethanol can be oxidized to form ethanal (also known as acetaldehyde). - The conversion of ethanol to ethanal can be represented by the following equation: ``` Ethanol + Oxygen → Ethanal + Water ```

4. Ethanal to Ethanoic Acid: - Ethanal can be further oxidized to form ethanoic acid (also known as acetic acid). - The conversion of ethanal to ethanoic acid can be represented by the following equation: ``` Ethanal + Oxygen → Ethanoic Acid + Water ```

5. Ethanoic Acid to Sodium Ethanoate: - Ethanoic acid can react with sodium hydroxide to form sodium ethanoate. - The conversion of ethanoic acid to sodium ethanoate can be represented by the following equation: ``` Ethanoic Acid + Sodium Hydroxide → Sodium Ethanoate + Water ```

Please note that these equations represent the general conversions mentioned in the given scheme. The actual reaction conditions and specific reagents may vary depending on the experimental setup or industrial processes.
