Question

Fe->Fe2O3->FeCl3->Fe(OH)3 составить генетический ряд металлов

Answer 1

4Fe+3O2=2Fe2O3
Fe2O3+6HCl=2FeCl3+3H2O
FeCl3+3NaOH=Fe (OH)3+3NaCl

Answer 2

Genetic Series of Metals

The genetic series of metals refers to the arrangement of metals in a sequence based on their reactivity with certain compounds or elements. In the given sequence Fe -> Fe2O3 -> FeCl3 -> Fe(OH)3, the reactivity of iron (Fe) with oxygen (O), chlorine (Cl), and hydroxide (OH) ions is demonstrated. This sequence can be used to understand the relative reactivity of iron with these substances.

The genetic series of metals is often used to predict the displacement reactions and the relative reactivity of metals in various chemical reactions.

Reactivity Series of Metals

The reactivity series of metals is a commonly used concept in chemistry to arrange metals in order of their reactivity. This series helps predict the outcome of displacement reactions and the likelihood of a metal displacing another metal from a compound.

The reactivity series of metals, in decreasing order of reactivity, is as follows: 1. Potassium (K) 2. Sodium (Na) 3. Calcium (Ca) 4. Magnesium (Mg) 5. Aluminum (Al) 6. Carbon (C) 7. Zinc (Zn) 8. Iron (Fe) 9. Tin (Sn) 10. Lead (Pb) 11. Hydrogen (H) 12. Copper (Cu) 13. Mercury (Hg) 14. Silver (Ag) 15. Gold (Au) 16. Platinum (Pt)

This series is a useful tool in understanding and predicting the behavior of metals in various chemical reactions.

Conclusion

The genetic series of metals, as demonstrated by the given sequence Fe -> Fe2O3 -> FeCl3 -> Fe(OH)3, provides insight into the reactivity of iron with oxygen, chlorine, and hydroxide ions. Additionally, the reactivity series of metals offers a broader understanding of the relative reactivity of various metals in chemical reactions.
