a) \(n_{HCl}=\frac{14,6}{36,5}=0,4\left(mol\right)\)
\(MnO_2+4HCl\rightarrow MnCl_2+Cl_2+2H_2O\)
0,1_______0,4______0,1______0,1____0,2(mol)
\(V_{Cl_2}=0,1.22,4=2,24\left(l\right)\)
b) đề sai ko z
a) n HC1=14,6/36,5=0,4(mol)
4HCl+MnO2------>Cl2+MnCl2+2H2O
0,4-------------------0,1
V Cl2=0,1.22,4=2,24(l)
b) n HCl=54,75/36,5=1,5(mol)
8HCl+K2MnO2----->2Cl2+4H2O+2KCl+MnCl2
1,5------------------------->0,375(mol)
V Cl2 = 0,375.22,4=8,4(l)
Chúc bạn hcoj tốt
a) nHCl=14,6\36,5=0,4(mol)
MnO2+4HCl→MnCl2+Cl2+2H2O
0,1_______0,4______0,1______0,1____0,2(mol)
VCl2=0,1.22,4=2,24(l)
nHCl=54,75\36,5=1,5 mol
16HCl | + | 2KMnO4 | → | 5Cl2 | + | 8H2O | + | 2KCl | + | 2MnCl2 |
1,5 ----------------------0,47 mol
VCl2=0,47 .22,4 =10,5 l
