Answer 2

It appears that you've listed a series of chemical reactions involving magnesium (Mg) and other substances. Let's break down these reactions step by step:

1. Mg → MgO: This reaction represents the oxidation of magnesium (Mg) to form magnesium oxide (MgO). This is a common reaction when magnesium metal is exposed to oxygen in the air.

   2Mg + O2 → 2MgO

   In this reaction, two atoms of magnesium (2Mg) react with one molecule of oxygen (O2) to form two molecules of magnesium oxide (2MgO).

2. MgO → Mg(OH)2: This reaction involves the conversion of magnesium oxide (MgO) into magnesium hydroxide (Mg(OH)2) through a reaction with water (H2O).

   MgO + H2O → Mg(OH)2

   In this reaction, magnesium oxide reacts with water to form magnesium hydroxide.

3. Mg(OH)2 → Mg3(PO4)2: This appears to be the formation of magnesium phosphate (Mg3(PO4)2) from magnesium hydroxide (Mg(OH)2) and phosphate ions (PO4^2-). The balanced chemical equation for this reaction would depend on the specific conditions and reactants involved, as phosphate reactions can vary. However, the general reaction can be represented as:

   3Mg(OH)2 + 2H3PO4 → Mg3(PO4)2 + 6H2O

   In this equation, three molecules of magnesium hydroxide react with two molecules of phosphoric acid (H3PO4) to produce magnesium phosphate and six molecules of water.

Please note that these reactions are simplified representations, and the actual conditions, concentrations, and reactants used can affect the specific reactions and products obtained. Additionally, chemical reactions can proceed differently depending on the temperature, pressure, and other factors. If you have more specific information or context about these reactions, please provide it for a more accurate explanation.
