CaCO₃ \(\rightarrow\) CaO \(\rightarrow\) CaC₂ \(\rightarrow\) C₂H₂ \(\rightarrow\) C₂H₄ \(\rightarrow\) C₂H₅OH \(\rightarrow\) CH₃COOH \(\rightarrow\) CH₃COOC₂H₅ \(\rightarrow\) CH₃COONa .

HELP ME !!!!!!

Answer 1

\(CaCO_3\underrightarrow{t^o}CaO+CO_2\)

\(5C+2CaO\underrightarrow{t^o}2CaC_2+CO_2\)

CaC₂ + 2H₂O \(\rightarrow\)C₂H₂ + Ca(OH)₂

\(C_2H_2+H_2\xrightarrow[Pd]{t^o}C_2H_4\)

\(C_2H_4+H_2O\underrightarrow{H^+}C_2H_5OH\)

\(C_2H_5OH+O_2\underrightarrow{mengiam}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH\xrightarrow[H^+]{t^o}CH_3COOC_2H_5+H_2O\)

CH₃COOC₂H₅ + NaOH \(\rightarrow\)CH₃COONa + C₂H₅OH

Answer 2

\(CaCO_3\underrightarrow{t^0}CaO+CO_2\)

\(5C+2CaO\underrightarrow{t^0}2CaC_2+CO_2\)

\(CaC_2+2H_2O\rightarrow C_2H_2+Ca\left(OH\right)_2\)

\(C_2H_2+H_2\xrightarrow[pd]{t^0}C_2H_4\)

\(C_2H_4+H_2O\underrightarrow{H+}C_2H_5OH\)

\(C_2H_5OH+O_2\underrightarrow{mengiam}CH_3COOH+H_2O\)

\(CH_3COOH+C_2H_5OH\xrightarrow[H+]{t^0}CH_3COOC_2H_5+H_2O\)

\(CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\)
