Question

giúp mik nhé, cảm mơn nhìu

Answer 1

\(n_{Na_2O}=\dfrac{6,2}{62}=0,1\left(mol\right)\\ a.Na_2O+H_2O\rightarrow2NaOH\\ 2NaOH+CuSO_4\rightarrow Na_2SO_4+Cu\left(OH\right)_2\\ Cu\left(OH\right)_2\underrightarrow{^{to}}CuO+H_2O\\ b.n_{CuO}=n_{Cu\left(OH\right)_2}=\dfrac{n_{NaOH}}{2}=n_{Na_2O}=0,1\left(mol\right)\\ \Rightarrow m_Y=m_{CuO}=0,1.80=8\left(g\right)\\ CuO+CO\underrightarrow{^{to}}Cu+H_2O\\ n_{CO}=n_{CuO}=0,1\left(mol\right)\\ V_{CO\left(đktc\right)}=0,1.22,4=2,24\left(l\right)\)

Answer 2

nNa2O=6,262=0,1(mol)a.Na2O+H2O→2NaOH2NaOH+CuSO4→Na2SO4+Cu(OH)2Cu(OH)2to→CuO+H2Ob.nCuO=nCu(OH)2=nNaOH2=nNa2O=0,1(mol)⇒mY=mCuO=0,1.80=8(g)CuO+COto→Cu+H2OnCO=nCuO=0,1(mol)VCO(đktc)=0,1.22,4=2,24(l)
