Answer: Decomposition

Explanation:

1. Synthesis is a chemical reaction in which two or more reactants combine to combine to give a single product.

2Mg+O_2\rightarrow 2MgO

2. Decomposition reaction is a chemical reaction in which one reactant gives two or more than two products on absorption of energy.

2H_2O_2\rightarrow 2H_2O+O_2

3.. Combustion is a chemical reaction in which hydrocarbon burns in the the presence of oxygen to form carbon dioxide, water and energy.

C_3H_8+5O_2\rightarrow 3CO_2+4H_2O

<u>Answer:</u> The net ionic equation is written below.

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of magnesium nitrate and aqueous ammonia (ammonium hydroxide) is given as:

Mg(NO_3)_2(aq.)+2NH_4OH(aq.)\rightarrow Mg(OH)_2(s)+2NH_4NO_3(aq.)

A white precipitate of magnesium hydroxide is formed in the above reaction.

Ionic form of the above equation follows:

Mg^{2+}(aq.)+2NO_3^-(aq.)+2NH_4^+(aq.)+2OH^-(aq.)\rightarrow Mg(OH)_2(s)+2NH_4^+(aq.)+2NO_3^-(aq.)

As, ammonium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

Mg^{2+}(aq.)+2OH^-(aq.)\rightarrow Mg(OH)_2(s)

Hence, the net ionic equation is written above.
