a,pthh:2Fe+3Cl2--->2FeCl3
b,nFe=11,2/56=0,2(mol)
từ pthh nCl2=\(\dfrac{3}{2}\)nFe=\(\dfrac{3}{2}.0,2=0,3\left(mol\right)\)
VCl2=0,3.22,4=6,72(l)
c,nCl2=14,4/22,4\(\dfrac{14,4}{22,4}=\dfrac{9}{14}\)(mol)
từ pthh nFe=\(\dfrac{2}{3}\)nCl2=\(\dfrac{9}{14}.\dfrac{2}{3}=\dfrac{3}{7}\)
mFe=56.\(\dfrac{3}{7}\)=24(g)
