Question

CO2 + H2O-------(фотосинтез) A------(брожение -CO2)B------(HBr)C-------(KOH/ -H2O)D

Answer 1

6CO₂ + 6H₂O = C₆H₁₂O₆(А) + 6O₂↑

C₆H₁₂O₆ = С₂H₅OH(B) + CO₂↑

С₂H₅OH + HBr = С₂H₅Br(C) + H₂O

С₂H₅Br + KOH(спирт.) = СH₂=CH₂(D) + KBr + H₂O

Answer 2

The chemical equations you provided seem to depict a series of reactions involving different compounds. Let's break them down step by step:

1. CO2 + H2O → A (through photosynthesis) This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O) react in the presence of light energy to produce a complex organic compound called A. Photosynthesis is the primary process by which plants and some other organisms convert sunlight into chemical energy.

2. A → B (through fermentation) The second equation suggests that compound A undergoes fermentation, a metabolic process carried out by certain microorganisms, such as yeast or bacteria. Fermentation typically involves the conversion of sugars or other organic compounds into simpler substances, often including the production of ethanol or other byproducts. In this case, A is converted into compound B.

3. B + HBr → C According to this equation, compound B reacts with hydrogen bromide (HBr) to form compound C. Without further information about the reaction conditions or specific mechanisms involved, it is challenging to provide more details about this particular step.

4. C + KOH (-H2O) → D The final equation indicates that compound C reacts with potassium hydroxide (KOH), with the elimination of water (-H2O), to yield compound D. Again, without additional context or details, it's difficult to provide specific information about the reaction mechanism or properties of compound D.

It's worth noting that while the equations you provided demonstrate a sequential series of reactions, in practice, there may be additional steps, intermediates, or side reactions that could influence the overall process. Furthermore, the names and properties of compounds A, B, C, and D are not specified, making it challenging to provide more precise explanations.
