CuSO4+2NaOH-->Cu(OH)2+Na2SO4
Cu(OH)2-->CuO+H2O
n\(_{CuSO4}=0,1.1=0,1\left(mol\right)\)
n\(_{NaOH}=0,2.1,5=0,3\left(mol\right)\)
=> NaOH dư
Theo pthh1
n\(_{Cu\left(OH\right)2}=n_{CuSO4}=0,1\left(mol\right)\)
Theo pthh2
n\(_{CuO}=n_{Cu\left(OH\right)2}=0,1\left(mol\right)\)
m CuO =0,1.80=8(g)
Ta có : \(nCuSO4=0,1\left(mol\right);nNaOH=0,3\left(mol\right)\)
\(\)\(\text{CuSO+NaOH }\rightarrow\text{Cu(OH)2+Na2SO4}\)
\(Cu\left(OH\right)2\rightarrow CuO+H2O\)
Lập tỉ lệ => NaOH dư
Ta có \(nCa\left(OH\right)2=nCuSO4=0,1\left(mol\right)\)
Mà \(nCuO=nCu\left(OH\right)2=0,1\left(mol\right)\)
\(\Rightarrow mCuO=8g\)
nCuSO4 = 0.1*1 = 0.1 mol
nNaOH = 0.3 mol
2NaOH + CuSO4 --> Na2SO4 + Cu(OH)2
0.2_______0.1_________________0.1
Cu(OH)2 -to-> CuO + H2O
0.1__________0.1
mCuO = 0.1*80 = 8 g
