Carry out the genetic series of transformations CuCl2 – FeCl2 – Fe (OH) 2 – Fe (NO3) 3 – NO2

1.CuCl2 + Fe = FeCL2 + Cu iron displaces copper, as it stands to the left in the series of voltages
2. FeCl2 + 2NaOH = Fe (OH) 2 + 2NaCl exchange reaction
3.4Fe (OH) 2 + 2H2O + O2 = 4Fe (OH) 3 increase the valence of iron
Fe (OH) 3 + 3HNO3 = Fe (NO3) 3 + 3H2O
Add acid and get salt
4.4Fe (NO3) 3 = 2Fe2O3 + 12NO2 + 3O2
Under temperature we decompose the nitric acid salt and get NO2 gas
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
