Question

Na+Br2 ->NaBrMg+O2->MgOFe+O2->Fe3O4Al+S->Al2S3​

Answer 1

Ответ:

Объяснение:

2Na + Br2 = 2NaBr

2Mg + O2 = 2MgO

3Fe + 2O2 = Fe3O4

2Al + 3S = Al2S3

Answer 2

It appears that you've provided a series of chemical reactions:

1. Na + Br2 -> NaBr
2. Mg + O2 -> MgO
3. Fe + O2 -> Fe3O4
4. Al + S -> Al2S3

These reactions represent the combination of different elements to form various compounds. Let's break down each reaction:

1. Sodium (Na) reacts with bromine (Br2) to form sodium bromide (NaBr): 2 Na + Br2 -> 2 NaBr

2. Magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO): 2 Mg + O2 -> 2 MgO

3. Iron (Fe) reacts with oxygen (O2) to form iron(II,III) oxide, commonly known as magnetite (Fe3O4): 3 Fe + 4 O2 -> 2 Fe3O4

4. Aluminum (Al) reacts with sulfur (S) to form aluminum sulfide (Al2S3): 2 Al + 3 S -> Al2S3

These are balanced chemical equations that represent the reactions you've described. If you have any specific questions or need more information about these reactions, please feel free to ask.
