Объяснение:
1) CaCO₃ (t°) → CaO + H₂O
2) CaO + 3C (t°) → CaC₂ + CO↑
3) CaC₂ + 2H₂O → C₂H₂↑ + Ca(OH)₂↓
4) C₂H₂ + H₂ (t°) → C₂H₄
5) C₂H₄ + HCl → C₂H₅Cl
6) 2C₂H₅Cl + 2NaOH → C₄H₈ + 2NaCl + 2H₂O
Ответ:
CaCO3→CaO→CaC2→C2H2→C2H4→C2H5Cl→C4H8
CaCO3 → CaO+CO2
CaO+3C → CaC2+CO
CaC2+2H2O → Ca(OH)2+C2H2
C2H2+H2 → C2H4
C2H4+HCl → C2H5Cl
2C2H5Cl + 2NaOH → C4H8 + 2NaCl + 2H2O
