a) \(CuO+H_2SO_4\rightarrow CuSO_4+H_2O\)
b) mdd sau pư = 1,6 + 100 = 101,6 (g)
c)
\(n_{CuO}=\dfrac{1,6}{80}=0,02\left(mol\right)\); \(n_{H_2SO_4}=\dfrac{100.9,8\%}{98}=0,1\left(mol\right)\)
Xét tỉ lệ: \(\dfrac{0,02}{1}< \dfrac{0,1}{1}\) => CuO hết, H2SO4 dư
Theo PTHH: \(n_{CuSO_4}=n_{CuO}=0,02\left(mol\right)\Rightarrow m_{CuSO_4}=0,02.160=3,2\left(g\right)\)
=> \(C\%_{CuSO_4}=\dfrac{3,2}{101,6}.100\%=3,15\%\)
