Question

KMnO4–O2–MgO—Mg(OH)2

Answer 1

Ответ:

KMnO4 - > K2MnO4 + MnO2 + O2

2Mg + O2 - > 2MgO

MgO + H2O - > Mg(OH)2

Answer 2

Відповідь:      KMnO4–O2–MgO—Mg(OH)2

2KMnO4 →t°→K2MnO4 + MnO2 + O2↑   

2Mg + O2 →t°→ 2MgO- реакция протекает при t°=600-650°С 

MgO + H2O→t°→ Mg(OH)2-реакция с образованием гидроксида магния протекает при t°=100-125°С

Answer 3

The chemical equation you provided is not balanced. However, I assume you are referring to the reaction between potassium permanganate (KMnO4), oxygen (O2), and magnesium oxide (MgO) to form magnesium hydroxide (Mg(OH)2).

The balanced equation for the reaction would be:

2KMnO4 + 3O2 + 2MgO → 2Mg(OH)2 + 2K2MnO4

In this reaction, two molecules of potassium permanganate react with three molecules of oxygen and two molecules of magnesium oxide to produce two molecules of magnesium hydroxide and two molecules of potassium manganate.

It's worth noting that the reaction between KMnO4, O2, and MgO is not a common reaction. Potassium permanganate is typically used as an oxidizing agent, and it reacts with various substances under different conditions. If you have a specific context or purpose for this reaction, please provide more details, and I'll be happy to assist you further.
