Fe+ H2SO4\(\rightarrow\)FeSO4+H2
\(n_{Fe}=n_{H_2SO_4}=n_{H_2}=\dfrac{2,24}{22,4}=0,1mol\)
mFe=0,1.56=5,6g
\(C_{M_{H_2SO_4}}=\dfrac{n}{V}=\dfrac{0,1}{0,2}=0,5M\)
a.Fe+H2SO4->FeSO4+H2
nH2=2,24/22,4=0,1(mol)
=>nFe=0,1(mol)=>mFe=0,1*56=5,6(g)
b.nH2SO4=0,1(mol)
=>CMH2SO4=0,1/0,2=0,05(M)
PTHH: Fe+ H2SO4-> FeSO4 + H2
a) nFe = nH2SO4 = nH2
--> nH2 = \(\dfrac{2,24}{22,4}\) = 0,1 mol
--> mFe = 0,1. 56 = 5,6 (g)
b) CM(H2SO4) = \(\dfrac{n}{V}\) = \(\dfrac{0,1}{0,2}\) = 0,5M
