Question

H2C=CH2->A->B->C4H10->CO2

Answer 1

1) CH2=CH2 + HCl = CH3-CH2Cl
2) 2CH3-CH2Cl + 2Na = 2NaCl + CH3-CH2-CH2-CH3 (бутан)
3) 2C4H10 + 13O2 = 8CO2 + 10H2O

Answer 2

It seems like you've provided a sequence of chemical reactions in a symbolic form. Let's break down the reactions step by step:

1. H2C=CH2 → A
2. A → B
3. B → C4H10
4. C4H10 → CO2

However, the symbols you've used (H2C=CH2) are not typical representations of chemical compounds or reactions. In standard chemical notation, compounds are represented using molecular formulas (e.g., C4H10 for butane) and reactions are depicted with appropriate reactant and product formulas.

If you could provide the actual molecular formulas or specific reactions you're referring to, I'd be happy to help you understand or explain the chemistry involved.
