Question

NA>NA2O>NAOH>NA2SO4​

Answer 1

Ответ:

4Na+O2=2Na2O

Na2O+H2O=NaOh+H2

NaOH+H2SO4=Na2SO4+H2O

Answer 2

The given sequence: NA > NA2O > NAOH > NA2SO4 represents the order of reactivity or basicity of sodium (Na) with various compounds. Let's interpret this sequence:

1. NA (Sodium): This represents the least reactive or least basic form of sodium. It is the elemental form of sodium, and it is relatively unreactive compared to its compounds.

2. NA2O (Sodium Oxide): Sodium oxide is more reactive than elemental sodium. It is a basic oxide, which means it can react with water to form a basic solution of sodium hydroxide (NaOH).

3. NAOH (Sodium Hydroxide): Sodium hydroxide is a strong base and is more reactive than sodium oxide. It is commonly known as caustic soda and is used in various industrial processes and chemical reactions.

4. NA2SO4 (Sodium Sulfate): Sodium sulfate is the most reactive or the strongest base among the compounds listed. It is a salt that can be derived from the reaction of sodium hydroxide (NaOH) with sulfuric acid (H2SO4).

In summary, the reactivity or basicity of sodium increases in the order: Sodium (Na) < Sodium Oxide (Na2O) < Sodium Hydroxide (NaOH) < Sodium Sulfate (Na2SO4).
