2) hoàn thành phản ứng hóa học:

b) H₂O + .......→ C₂H₂+............

e) .........→ C₂H₅OH +........

h) + H₂O → ......+.........

m) +.......→ CO_{2 +.........}

_n) C₂H₅OH +.........→ H₂ +...........

Answer 1

câu 2

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

e)C6H12O6\(\rightarrow\)2C2H5OH+2CO2

n)C2H5OH +2Na\(\rightarrow\)2C2H5ONa+H2

CÂU 1

Answer 2

1. \(2CH_3COOH+Zn\rightarrow\left(CH_3COO\right)_2Zn+H_2\)

\(\left(CH_3COO\right)_2Zn+2HCl\rightarrow ZnCl_2+2CH_3COOH\)

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

e) \(C_6H_{12}O_6\xrightarrow[30-35^oC]{menruou}2C_2H_5OH+2CO_2\)

h) \(C_2H_5Br+H_2O\rightarrow C_2H_5OH+HBr\)

m) \(CH_4+2O_2\underrightarrow{t^o}CO_2+2H_2O\)

n) \(C_2H_5OH+Na\rightarrow C_2H_5ONa+\dfrac{1}{2}H_2\)
