PTHH : CuO + H2 -> (t*) Cu + H2O
Theo đề bài ta có : nCuO = \(\dfrac{m}{M}=\dfrac{1.6}{80}=0.02\left(mol\right)\)
Theo PTHH \(n_{H_2}\) = nCuO = 0,02 ( mol )
=> \(V_{H_2}=n.22,4=0,02.22,4=0,448\left(l\right)\)
Vậy...
CuO + H2 → Cu + H2O
\(n_{CuO}=\dfrac{1,6}{80}=0,02\left(mol\right)\)
Theo PT: \(n_{H_2}=n_{CuO}=0,02\left(mol\right)\)
\(\Rightarrow V_{H_2}=0,02\times22,4=0,448\left(l\right)\)
