Answer 1

Объяснение:

Na2O, it has not acidic properties but have based:

Na2O + h2so4 = na2so4 + h2o

Answer 2

It seems like you're looking for the oxide formulas, hydroxide formulas, and their corresponding acidic properties, as well as how these properties can be confirmed using chemical reactions involving sodium hydroxide (NaOH). I'll provide you with a list of common oxides and their corresponding hydroxides, along with information about their acidic properties and reactions with NaOH.

1. Oxide: Carbon Dioxide (CO2)

   • Hydroxide: Water (H2O)
   • Acidic Properties: Carbon dioxide is non-metallic oxide and is not acidic in itself.
   • Reaction with NaOH: No direct reaction. Carbon dioxide doesn't react with sodium hydroxide.

2. Oxide: Sulfur Dioxide (SO2)

   • Hydroxide: Sulfuric Acid (H2SO4)
   • Acidic Properties: Sulfur dioxide dissolves in water to form sulfurous acid, which is a weak acid.
   • Reaction with NaOH: SO2 + 2 NaOH → Na2SO3 + H2O

3. Oxide: Nitrogen Dioxide (NO2)

   • Hydroxide: Nitric Acid (HNO3)
   • Acidic Properties: Nitrogen dioxide reacts with water to form nitric acid, a strong acid.
   • Reaction with NaOH: 3 NO2 + 6 NaOH → 3 NaNO3 + 3 H2O

4. Oxide: Phosphorus Pentoxide (P4O10)

   • Hydroxide: Phosphoric Acid (H3PO4)
   • Acidic Properties: Phosphorus pentoxide reacts with water to form phosphoric acid, which is a weak acid.
   • Reaction with NaOH: P4O10 + 12 NaOH → 4 Na3PO4 + 6 H2O

5. Oxide: Sulfur Trioxide (SO3)

   • Hydroxide: Sulfuric Acid (H2SO4)
   • Acidic Properties: Sulfur trioxide reacts with water to form sulfuric acid, a strong acid.
   • Reaction with NaOH: SO3 + 3 NaOH → Na2SO4 + 3 H2O

6. Oxide: Aluminum Oxide (Al2O3)

   • Hydroxide: Aluminum Hydroxide (Al(OH)3)
   • Acidic Properties: Aluminum oxide is amphoteric, meaning it can exhibit both acidic and basic properties depending on the conditions.
   • Reaction with NaOH: Al2O3 + 6 NaOH + 3 H2O → 2 Na3Al(OH)6

Remember that the concept of acidity depends on the behavior of the substances in water and their ability to donate or accept protons (H+ ions). In these cases, the hydroxides serve as acid sources in water.

Please note that the equations I've provided are simplified representations of the chemical reactions and might not include all the intermediate steps. Also, there are various factors that can influence the reactivity and behavior of these substances, such as concentration and temperature.
