pt Fe+2HCl\(\rightarrow\)FeCl2+H2
A) nH2 =\(\dfrac{16,8}{22,4}\)=0,75 mol
theo pt nFe =nH2=0,75 MOL \(\Rightarrow\)m Fe =0.75*56=42 g
theo pt nHCl =2 n H2=1,5 mol \(\Rightarrow\)mHCL=54,75 g
B )theo pt nFeCl2=nH2=0,75g \(\Rightarrow\)mFeCl2=95,25 g
Fe +2HCl \(\rightarrow\)FeCl2 +H2
nH2 =16,8/22,4=0,75 mol
theo pt nFe=nH2=0,75 MOL
suy ra mFe=0,75*56=42g
theo pt nHCl=2nH2 =1.5 mol
suy ra mHCl=54,75 g
nFeCl2=nH2 =0,75 g
suy ra mFeCl2=95,25g
