Question

Mg➡ MgO➡MgSO4➡MgCl2​

Answer 1

Объяснение:

2Mg+O2= 2MgO

MgO+H2SO4= MgSO4+H2O

MgSO4+2HCl= MgCl2+H2SO4

Answer 2

It looks like you've provided a sequence of chemical reactions involving magnesium (Mg) and various compounds. Let's break down each step of the sequence:

1. Mg: This represents elemental magnesium, which is a metallic element with the chemical symbol Mg. It's a reactive metal commonly found in nature.

2. MgO: This represents magnesium oxide. It forms when magnesium reacts with oxygen (O2), typically through combustion or exposure to air. The reaction can be represented as:
   2Mg + O2 -> 2MgO

3. MgSO4: This represents magnesium sulfate. Magnesium sulfate is a compound that contains magnesium, sulfur, and oxygen. It's often encountered as Epsom salt. It can be produced by reacting magnesium oxide (MgO) with sulfuric acid (H2SO4):
   MgO + H2SO4 -> MgSO4 + H2O

4. MgCl2: This represents magnesium chloride. Magnesium chloride is a compound formed by the reaction between magnesium and hydrochloric acid (HCl):
   Mg + 2HCl -> MgCl2 + H2

The sequence you've provided represents the transformation of magnesium through these chemical reactions, resulting in the formation of magnesium oxide, magnesium sulfate, and magnesium chloride. These reactions demonstrate how magnesium can react with various compounds to form different chemical products.
