Question

Giúp mik vs ạ cần gấp

Answer 1

nH2=4.48/22.4=0.2 mol

pt fe + 2hcl ---- fecl2 + h2 (1)

theopt(1) nfe=nfecl2=nh2=o,2 mol

=> mfe=0,2.56=11,2g

=>mfecl2=0,2.127=25,4g

                                   

Answer 2

\(a.\) \(Fe+2HCl\rightarrow FeCl_2+H_2\)

\(b.n_{H_2}=\dfrac{4,48}{22,4}=0,2mol\)

\(m_{Fe}=0,2.56=11,2g\)

\(c.m_{FeCl_2}=0,2.127=25,4g\)
