I found this at WikiPedia. It's pretty close. Magnesium Hydroxide is Milk of Magnesia. They show Magnesium Hydroxide from a magnesium salt:
-----
The chemical formula of sodium hydroxide is NaOH.
The chemical formula of magnesium hydroxide is Mg(OH)2.
(NH4)3PO4 + 3NaOH -------> Na3PO4 + 3NH3 + 3H2O
The balanced chemical equation for this reaction is: 3Mg(NO3)2 + 2Na3PO4 -> 6NaNO3 + Mg3(PO4)2
The balanced equation for the formation of magnesium nitride is: 3Mg + N2 -> Mg3N2.
The equation for the reaction between phosphoric acid (H3PO4) and ammonium hydroxide (NH4OH) is: H3PO4 + NH4OH -> (NH4)3PO4 + H2O This balanced equation shows the chemical reaction where phosphoric acid reacts with ammonium hydroxide to form ammonium phosphate and water.
The reaction between ammonium phosphate and barium hydroxide will produce barium phosphate and ammonium hydroxide as products. This is a double displacement reaction where the cations and anions switch partners. The balanced chemical equation for this reaction is: (NH4)3PO4 + 3Ba(OH)2 → Ba3(PO4)2 + 6NH4OH.
No - phosphorous can not just appear.Heating magnesium hydroxide will give magnesium oxide and water.
(NH4)3PO4 + 3NaOH -------> Na3PO4 + 3NH3 + 3H2O
The balanced chemical equation for this reaction is: 3Mg(NO3)2 + 2Na3PO4 -> 6NaNO3 + Mg3(PO4)2
Mg(NO2)2 + 2NaOH --> Mg(OH)2 + 2NaNO2
The balanced chemical equation for the reaction between magnesium hydroxide and hydrochloric acid to form magnesium chloride and water is: Mg(OH)2 + 2HCl -> MgCl2 + 2H2O.
The balanced chemical equation is: MgO + H2O → Mg(OH)2 The product formed in this reaction is magnesium hydroxide.
The balanced equation for the reaction between sulfuric acid (H2SO4) and magnesium hydroxide (Mg(OH)2) is: H2SO4 + Mg(OH)2 -> MgSO4 + 2H2O.
Phosphoric acid and magnesium hydroxide react to form magnesium phosphate and water.
Mg(OH)2 + H2SO4 --> MgSO4 + 2H2O
There is no reaction between these, because all species are soluble.
When magnesium hydroxide reacts with sulfuric acid, it forms magnesium sulfate and water. The balanced chemical equation for this reaction is: Mg(OH)2 + H2SO4 → MgSO4 + 2H2O
The balanced equation for the combustion of magnesium is 2Mg + O2 -> 2MgO.
