Equations for the Transformation of Substances: Mg → MgO → Mg(OH)2 → Mg3(PO4)2

To describe the transformation of substances from Mg to MgO to Mg(OH)2 to Mg3(PO4)2, we can write a series of chemical equations. Let's break down each step:

1. Mg to MgO: - Magnesium (Mg) reacts with oxygen (O2) to form magnesium oxide (MgO). - The balanced chemical equation for this reaction is: 2Mg + O2 → 2MgO [[1]].

2. MgO to Mg(OH)2: - Magnesium oxide (MgO) reacts with water (H2O) to form magnesium hydroxide (Mg(OH)2). - The balanced chemical equation for this reaction is: MgO + H2O → Mg(OH)2 [[2]].

3. Mg(OH)2 to Mg3(PO4)2: - Magnesium hydroxide (Mg(OH)2) reacts with phosphoric acid (H3PO4) to form magnesium phosphate (Mg3(PO4)2). - The balanced chemical equation for this reaction is: 3Mg(OH)2 + 2H3PO4 → Mg3(PO4)2 + 6H2O [[3]].

Therefore, the overall transformation of substances from Mg to MgO to Mg(OH)2 to Mg3(PO4)2 can be represented by the following series of chemical equations:

2Mg + O2 → 2MgO

MgO + H2O → Mg(OH)2

3Mg(OH)2 + 2H3PO4 → Mg3(PO4)2 + 6H2O

I hope this helps! Let me know if you have any further questions.
