PTHH:
\(CuO+H_2\rightarrow\left(t^o\right)Cu+H_2O\)
x x x x
\(Fe_2O_3+3H_2\rightarrow\left(t^o\right)2Fe+3H_2O\)
y 3y 2y 3y
Ta có hệ PT:
\(\left\{{}\begin{matrix}x+y=\dfrac{9,916}{24,79}=0,4\\80x+160y=24\end{matrix}\right.\)
\(\Rightarrow x=y=0,1\) (mol)
\(m_{kl}=0,1.64+0,2.56=17,6\left(g\right)\)
\(n_{H_2}=\dfrac{9,916}{24,79}=0,4\left(mol\right)\)
\(CuO+H_2\underrightarrow{t^o}Cu+H_2O\)
x------> x ----> x
\(Fe_2O_3+3H_2\underrightarrow{t^o}2Fe+3H_2O\)
y---------> 3y ---> 2y
\(\left\{{}\begin{matrix}80x+160y=24\\x+3y=0,4\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}x=0,1\\y=0,1\end{matrix}\right.\)
\(m_{hh.kl.thu}=m_{Cu}+m_{Fe}=0,1.64+0,1.2.56=17,6\left(g\right)\)
