CuO+H2-to>Cu+H2O
0,2-----0,2
n CuO=\(\dfrac{16}{80}\)=0,2 mol
=>VH2=0,2.22,4=4,48l
\(n_{CuO}=\dfrac{m_{CuO}}{M_{CuO}}=\dfrac{16}{80}=0,2mol\)
\(CuO+H_2\rightarrow Cu+H_2O\)
0,2 0,2 ( mol )
\(V_{H_2}=n_{H_2}.22,4=0,2.22,4=4,48l\)
\(pthh:CuO+H_2\overset{t^o}{--->}Cu+H_2O\)
\(n_{CuO}=\dfrac{16}{80}=0,2\left(mol\right)\)
Theo pt: \(n_{H_2}=n_{CuO}=0,2\left(mol\right)\)
\(\Rightarrow V_{H_2}=0,2.22,4=4,48\left(lít\right)\)
