Answer 1

Na2O, Cao, Pb0, BaO це основні оксиди

Answer 2

Ответ:

BaO, Na2O, CaO,

Объяснение:

Это основные оксиды к этим оксдам есть те у которых ступень окисления не больше +3

Answer 3

SO3, ZnO, Na2O, CaO, CO2, PbO, BaO are the formulas of basic oxides.

Basic Oxides:

Basic oxides are compounds that react with water to form bases. They are typically metal oxides and are characterized by their ability to neutralize acids. Basic oxides are also known as basic anhydrides because they can react with water to form bases.

Here are the formulas of some common basic oxides:

- SO3: Sulfur trioxide is a basic oxide that reacts with water to form sulfuric acid (H2SO4) [[1]]. - ZnO: Zinc oxide is a basic oxide that reacts with water to form zinc hydroxide (Zn(OH)2) [[2]]. - Na2O: Sodium oxide is a basic oxide that reacts with water to form sodium hydroxide (NaOH) [[3]]. - CaO: Calcium oxide, also known as quicklime, is a basic oxide that reacts with water to form calcium hydroxide (Ca(OH)2) [[4]]. - CO2: Carbon dioxide is not a basic oxide. It is an acidic oxide that reacts with water to form carbonic acid (H2CO3) [[5]]. - PbO: Lead(II) oxide is a basic oxide that reacts with water to form lead(II) hydroxide (Pb(OH)2) [[6]]. - BaO: Barium oxide is a basic oxide that reacts with water to form barium hydroxide (Ba(OH)2) [[7]].

It's important to note that NaOH and H2CO3 are not basic oxides. NaOH is a base itself, while H2CO3 is an acidic oxide that reacts with water to form carbonic acid.

I hope this helps! Let me know if you have any further questions.
