nAl = \(\frac{10,8}{27}=\)0,4 (mol)
nHCl = \(\frac{200.7,3\%}{36,5}=\)0,4(mol)
PTHH : 2Al+ 6HCl---> 2AlCl3+ 3H2
Có:\(\frac{0,4}{2}>\frac{0,4}{6}\)=> Al dư.
=> nAlCl3= 0,4(mol)=> mAlCl3= 53,4(g)
2Al+ 6HCl--->2AlCl3 +3H2
Ta có
n\(_{Al}=\frac{10,8}{27}=0,4\left(mol\right)\)
n\(_{HCl}=\frac{200.7,3}{100.36,5}=0,4\left(mol\right)\)
=>HCl dư
Theo pthh
n\(_{AlCl3}=n_{Al}=0,4\left(mol\right)\)
m\(_{AlCl3}=0,4.133,5=53,4\left(g\right)\)
Chúc bạn học tốt
nAl = 0,4 (mol)
nHCl = 0,4(mol)
PTHH : 2Al+ 6HCl---> 2AlCl3+ 3H2
=> HCl dư
=> nAlCl3= 0,4(mol)=> mAlCL3= 53,4(g)
