Question

Answer 1

\(\left(1\right)2Fe+3Cl_2\underrightarrow{t^o}2FeCl_3\)

(2) \(FeCl_3+3AgNO_3\rightarrow Fe\left(NO_3\right)_3+3AgCl\downarrow\)

(3) \(Fe\left(NO_3\right)_3+3NaOH\rightarrow Fe\left(OH\right)_3\downarrow+3NaNO_3\)

(4) \(2Fe\left(OH\right)_3\underrightarrow{t^o}Fe_2O_3+3H_2O\)

Answer 2

\(2Fe+6HCl\rightarrow2FeCl_3+3H_2\)

\(FeCl_3+3HNO_3\rightarrow Fe\left(NO_3\right)_3+3HCl\)

\(Fe\left(NO_3\right)_3+3NaOH\rightarrow Fe\left(OH\right)_3+3NaNO_3\)

\(Fe\left(OH\right)_3\rightarrow Fe_2O_3+H_2O\)
