Question

Giúp mình mình cần gấp ạ !!!

Answer 1

\(\left(1\right)C_2H_2+H_2\xrightarrow[t^o]{Pd,PdCO_3}C_2H_4\\ \left(2\right)C_2H_4+H_2O\xrightarrow[t^o]{axit}C_2H_5OH\\ \left(3\right)C_2H_5OH+CH_3COOH\xrightarrow[t^o]{H_2SO_{4\left(đ\right)}}CH_3COOC_2H_5+H_2O\\ \left(5\right)2CH_3COOH+CaCO_3\rightarrow\left(CH_3COO\right)_2Ca+CO_2\uparrow+H_2O\)

Answer 2

\(C_2H_2+H_2\underrightarrow{t^o,Pd}C_2H_4\)

\(C_2H_4+H_2O\underrightarrow{t^o,xt:H_2SO_4}C_2H_5OH\)

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

\(CH_3COOH+C_2H_5OH\underrightarrow{t^o,xt:H_2SO_4}CH_3COOC_2H_5+H_2O\)\(2CH_3COOH+Ca\rightarrow\left(CH_3COO\right)_2Ca+H_2\)
