2)

a) $n_{CO_2} = \dfrac{16,8}{22,4} = 0,75(mol)$
$C_6H_{12}O_6 \xrightarrow{men\ rượu} 2CO_2 + 2C_2H_5OH$
$n_{glucozo} = \dfrac{1}{2}n_{CO_2} = 0,375(mol)$
$m_{glucozo} = 0,375.180 = 67,5(gam)$

b) $n_{C_2H_5OH} = n_{CO_2} = 0,75(mol)$
$m_{C_2H_5OH} = 0,75.46 = 34,5(gam)$

$V_{C_2H_5OH} = \dfrac{34,5}{0,8}=  43,125(ml)$

Câu 1:

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

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

\(CH_3COOH+Na\rightarrow CH_3COOH+\dfrac{1}{2}H_2\)

b, \(CH_3COOH+C_2H_5OH⇌CH_3COOC_2H_5+H_2O\) (xt: H2SO4 đặc, to)

Câu 2:

a, \(n_{CO_2}=\dfrac{16,8}{22,4}=0,75\left(mol\right)\)

\(C_6H_{12}O_6\underrightarrow{t^o,xt}2C_2H_5OH+2CO_2\)

Theo PT: \(n_{C_6H_{12}O_6}=\dfrac{1}{2}n_{CO_2}=0,375\left(mol\right)\)

\(\Rightarrow m_{C_6H_{12}O_6}=0,375.180=67,5\left(g\right)\)

b, \(n_{C_2H_5OH}=n_{CO_2}=0,75\left(mol\right)\Rightarrow m_{C_2H_5OH}=0,75.46=34,5\left(g\right)\)

\(\Rightarrow V_{C_2H_5OH}=\dfrac{34,5}{0,8}=43,125\left(ml\right)\)

a) 

\(Mg+\dfrac{1}{2}O_2\xrightarrow[]{t^o}MgO\)

\(MgO+2HCl\rightarrow MgCl_2+H_2O\)

\(MgCO_3+2HNO_3\rightarrow Mg\left(NO_3\right)_2+H_2O+CO_2\uparrow\)

\(Mg\left(NO_3\right)_2+2KOH\rightarrow2KNO_3+Mg\left(OH\right)_2\downarrow\)
