a)\(Fe+CuSO4-->Cu+FeSO4\)

b) \(n_{Fe}=\frac{1,96}{56}=0,035\left(mol\right)\)

\(m_{CuSO4}=\frac{100.10}{100}=10\left(g\right)\)

\(n_{CuSO4}=\frac{10}{160}=0,0625\left(mol\right)\)

Do \(0,036>0,0625\Leftrightarrow\) \(n_{Fe}< n_{CuSO4}\)

=> CuSO4 dư.Tính theo n chất hết (Fe)

Chất rắn B là Cu

\(n_{Cu}=n_{Fe}=0,035\left(mol\right)\)

\(m_{Cu}=0,035.64=2,24\left(g\right)\)

c) m dd A =\(m_{Fe}+m_{ddCuSO4}-m_{Cu}=1,96+100-2,24=99,72\left(g\right)\)

dd A là FeSO4 và CuSO4 dư

\(n_{FeSO4}=n_{Fe}=0,035\left(mol\right)\)

\(m_{FeSO4}=0,035.152=5,32\left(g\right)\)

\(C\%_{FeSO4}=\frac{5,32}{99,72}.100\%=5,33\%\)

\(n_{CuSO4}=n_{Fe}=0,035\left(mol\right)\)

\(n_{CuSO4}dư=0,0625-0,035=0,0275\left(mol\right)\)

\(m_{CuSO4}dư=0,0275.160=4,4\left(g\right)\)

\(C\%_{CuSO4}dư=\frac{4,4}{99,72}.100\%=4,41\%\)
