Answer 2

Formation of Magnesium Oxide (MgO)

The equation for the formation of magnesium oxide (MgO) can be represented as:

Mg + O2 → MgO

Formation of Magnesium Chloride (MgCl2)

The equation for the formation of magnesium chloride (MgCl2) can be represented as:

MgO + 2HCl → MgCl2 + H2O

Formation of Magnesium Hydroxide (Mg(OH)2)

The equation for the formation of magnesium hydroxide (Mg(OH)2) can be represented as:

MgCl2 + 2NaOH → Mg(OH)2 + 2NaCl

Formation of Water (H2O)

The equation for the formation of water (H2O) can be represented as:

Mg(OH)2 → H2O

Formation of Phosphoric Acid (H3PO4)

The equation for the formation of phosphoric acid (H3PO4) can be represented as:

H2O + P4O10 → 4H3PO4

Formation of Calcium Phosphate (Ca3(PO4)2)

The equation for the formation of calcium phosphate (Ca3(PO4)2) can be represented as:

3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O Therefore, the overall equation for the given scheme is:

Mg + O2 → MgO → MgCl2 → Mg(OH)2 → H2O → H3PO4 → Ca3(PO4)2 Please note that the equations provided are based on the information available from the search results.
