a, \(PTHH:CuCl_2+2NaOH\rightarrow Cu\left(OH\right)_2+2NaCl\)
b, Ta có:
\(n_{NaOH}=\frac{60}{40}=1,5\left(mol\right)\)
\(\Rightarrow n_{Cu\left(OH\right)2}=n_{NaOH}=0,75\left(mol\right)\)
\(\Rightarrow m_{Cu\left(OH\right)2}=0,75.98=73,5\left(g\right)\)
c, \(Cu\left(OH\right)_2+H_2SO_4\rightarrow CuSO_4+2H_2O\)
\(\Rightarrow n_{H2SO4}=0,75\left(mol\right)\)
\(\Rightarrow V_{dd\left(H2SO4\right)}=\frac{0,75}{0,5}=1,5\left(l\right)\)
