a, \(C_2H_5OH+Na\rightarrow C_2H_5ONa+\dfrac{1}{2}H_2\)
\(CH_3COOH+Na\rightarrow CH_3COONa+\dfrac{1}{2}H_2\)
b, Gọi: \(\left\{{}\begin{matrix}n_{C_2H_5OH}=x\left(mol\right)\\n_{CH_3COOH}=y\left(mol\right)\end{matrix}\right.\) ⇒ 46x + 60y = 15,2 (1)
Ta có: \(n_{H_2}=\dfrac{1}{2}n_{C_2H_5OH}+\dfrac{1}{2}n_{CH_3COOH}=\dfrac{1}{2}x+\dfrac{1}{2}y=\dfrac{3,36}{22,4}=0,15\left(mol\right)\left(2\right)\)
\(\Rightarrow\left\{{}\begin{matrix}x=0,2\left(mol\right)\\y=0,1\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}m_{C_2H_5OH}=0,2.46=9,2\left(g\right)\\m_{CH_3COOH}=0,1.60=6\left(g\right)\end{matrix}\right.\)
