Question

Fe+?=Fe(OH)3 Fe(OH)3+?=Fe2O3 Fe2O3+?=Fe

Answer 1

Ответ:

Объяснение:

1) из железа нельзя получить Fe(OH)3

2) 2Fe(OH)3 -> Fe2O3 + 3H2O

3) Fe2O3 + 3Mg = 3MgO +2 Fe

Answer 2

Let's balance the chemical equations step by step:

1. Fe + ? = Fe(OH)3

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation.

The balanced equation is: Fe + 3H2O = Fe(OH)3

2. Fe(OH)3 + ? = Fe2O3

Again, we need to balance the equation by making sure the number of atoms of each element is equal on both sides.

The balanced equation is: 2Fe(OH)3 = Fe2O3 + 3H2O

3. Fe2O3 + ? = Fe

Now, let's balance the last equation:

The balanced equation is: Fe2O3 + 3H2O = 2Fe + 3O2

Now all the chemical equations are balanced. If you have any other questions or need further assistance, feel free to ask!
