\(a/ CuO+2HCl \to CuCl_2+H_2O\\ b/\\ n_{CuO}=0,125(mol)\\ \to n_{HCl}=0,125.2=0,25(mol)\\ m_{HCl}=0,25.36,5=9,125(g)\\ c/\\ n_{CuO}=n_{CuCl_2}=0,125(mol)\\ CM_{CuCl_2}=\frac{0,125}{0,5}=0,25M\)
a) \(CuO+2HCl\rightarrow CuCl2+H2O\)
b) Ta có: \(n_{CuO}=\dfrac{10}{80}=0,8\left(mol\right)\)
Theo PT: \(n_{HCl}=2nCuO=1,6\left(mol\right)\)
\(\Rightarrow m_{HCl}=1,6.36,5=58,4\left(g\right)\)
c) \(n_{CuCl2}=n_{CuO}=0,8\left(mol\right)\)
\(V_{dd}=\)không đổi \(=500ml=0,5l\)
\(\Rightarrow C_{M\left(CuCl2\right)}=\dfrac{0,8}{0,5}=1,6\left(M\right)\)
