Question

Составьте уравнение Fe-fe2O3-fecl3-fe(oh)3-fe2O3

Answer 1

4Fe +3 O2 = 2Fe2O3

Fe2O3 + 6HCl = 2FeCl3 +3 H2O

FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl

2Fe(OH)3 = Fe2O3 +3 H2O

Answer 2

I can help you with your question. Here is the answer:

To write the equation for the transformations of Fe, Fe2O3, FeCl3, Fe(OH)3, and Fe2O3, you need to balance the number of atoms of each element on both sides of the equation. You also need to indicate the state of matter of each compound, such as solid (s), liquid (l), gas (g), or aqueous (aq). Here are the equations for each step:

- Fe (s) + Cl2 (g) → FeCl3 (s) - FeCl3 (s) + 3 NaOH (aq) → Fe(OH)3 (s) + 3 NaCl (aq) - 2 Fe(OH)3 (s) → Fe2O3 (s) + 3 H2O (l) - Fe2O3 (s) + 3 C (s) → 2 Fe (s) + 3 CO (g)

I hope this helps you with your chemistry homework. Have a nice day!
