\(n_{Cu}=\dfrac{8}{64}=0,125\left(mol\right)\)
PTHH: \(CO+CuO-t^o->Cu+CO_2\uparrow\)
a. Theo PT ta có: \(n_{CuO}=n_{Cu}=0,125\left(mol\right)\)
=> \(m_{CuO\left(pư\right)}=0,125.80=10\left(g\right)\)
b. Theo PT ta có: \(n_{CO_2}=n_{Cu}=0,125\left(mol\right)\)
=> \(V_{CO_2}=0,125.22,4=2,8\left(l\right)\)
a) \(n_{Cu}=\dfrac{8}{64}=0,125\left(mol\right)\)
PTHH: \(CuO+CO\underrightarrow{t^0}Cu+CO_2\uparrow\)
Theo PTHH: \(n_{CuO}:n_{Cu}=1:1\Rightarrow n_{CuO}=n_{Cu}=0,125\left(mol\right)\)
\(\Rightarrow m_{CuO}=0,125.80=10\left(g\right)\)
b) Theo PTHH: \(n_{CO_2}:n_{Cu}=1:1\Rightarrow n_{CO_2}=n_{Cu}=0,125\left(mol\right)\)
\(\Rightarrow V_{CO_2\left(đktc\right)}=0,125.22,4=2,8\left(l\right)\)
