Question

Al + Br2→ AlBr3Pb +02— Pb3О4FeO + О2, → Fe2О3​

Answer 1

Ответ:

Объяснение:

3Al + 3Br₂= 2AlBr₃

3Pb +2O₂= Pb₃О₄

4FeO + О₂= 2Fe₂О₃​

Answer 2

It looks like you've written a few chemical equations. Let's balance them one by one:

1. Al + Br2 → AlBr3 This equation is already balanced.

2. Pb + O2 → Pb3O4 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:

Pb + 2O2 → Pb3O4

3. FeO + O2 → Fe2O3 Similarly, for this equation:

4FeO + 3O2 → 2Fe2O3

Now, the balanced chemical equations are as follows:

1. 2Al + 3Br2 → 2AlBr3
2. Pb + 2O2 → Pb3O4
3. 4FeO + 3O2 → 2Fe2O3
