Ta có: \(n_{Fe}=\dfrac{5,6}{56}=0,1\left(mol\right)\)
PT: \(Fe+H_2SO_4\rightarrow FeSO_4+H_2\)
___0,1______________0,1____0,1 (mol)
\(FeSO_4+BaCl_2\rightarrow FeCl_2+BaSO_{4\downarrow}\)
__0,1______0,1_____________0,1 (mol)
a, VH2 = 0,1.22,4 = 2,24 (l)
b, \(V_{BaCl_2}=\dfrac{0,1}{0,2}=0,5\left(l\right)\)
c, \(m_{BaSO_4}=0,1.233=23,3\left(g\right)\)
