\(n_{CuO\left(pư\right)}=\dfrac{48.80\%}{80}=0,48\left(mol\right)\)
\(n_{CuO\left(bđ\right)}=\dfrac{48}{80}=0,6\left(mol\right)\)
PTHH: \(CuO+H_2\underrightarrow{t^o}Cu+H_2O\)
0,48->0,48->0,48
Chất rắn sau pư gồm \(\left\{{}\begin{matrix}CuO:0,12\left(mol\right)\\Cu:0,48\left(mol\right)\end{matrix}\right.\)
=> mchất rắn sau pư = 0,12.80 + 0,48.64 = 40,32 (g)
\(V_{H_2}=0,48.22,4=10,752\left(l\right)\)
\(n_{CuO}=\dfrac{48}{80}=0,6\left(mol\right)\)
Vì H = 80%
=> \(\left\{{}\begin{matrix}n_{CuO\left(pư\right)}=0,6.80\%=0,48\left(mol\right)\\n_{CuO\left(chưa.pư\right)}=0,6-0,48=0,12\left(mol\right)\end{matrix}\right.\)
PTHH: CuO + H2 --to--> Cu + H2O
0,48--->0,48--->0,48
=> mchất rắn sau pư = 0,48.64 + 0,12.80 = 40,32 (g)
VH2 = 0,48.22,4 = 10,752 (l)
