\(Fe2O3+6HCl-->2FeCl3+3H2O\)
b) \(n_{Fe2O3}=\frac{48}{160}=0,3\left(mol\right)\)
\(n_{HCl}=6n_{Fe2O3}=1,8\left(mol\right)\)
\(m_{HCl}=1,8.36,5=65,7\left(g\right)\)
c) \(n_{FeCl3}=2n_{Fe2O3}=0,6\left(mol\right)\)
\(m_{FeCl3}=0,6.162,5=97,5\left(g\right)\)
a)\(Fe_2O_3+6HCl\rightarrow2FeCl_3+3H_2O\)
b)\(n_{Fe_2O_3}=\frac{48}{160}=0,3\left(mol\right)\)
Theo PT: \(n_{HCl}=6n_{Fe_2O_3}=1,8\left(mol\right)\)
\(\Rightarrow m_{Fe_2O_3}=1,8.36,5=65,7\left(g\right)\)
c) Theo PT: \(n_{FeCl_3}=2n_{Fe_2O_3}=0,6\left(mol\right)\)
\(\Rightarrow m_{FeCl_3}=0,6.162,5=97,5\left(g\right)\)
