Question

обгрунтуйте чи будуть вищи оксиди елементив з атомними номерами 6,11,18,взаемодияти з кислотою ,напишить ривнняня можливих реакций,

Answer 1

Объяснение:

Атомное число углерода 6, высший оксид углерода это СО2, кислотный оксид не вступает в реакцию с кислотами.

Атомное число аргона 18, благородный газ аргон, с кислородом не образовывает оксиды.

Атомное число натрия 11… Высший оксид натрия Na2O + 2HNO3 → 2NaNO3 + H2O

Answer 2

Higher Oxides of Elements with Atomic Numbers 6, 11, and 18

The elements with atomic numbers 6, 11, and 18 are carbon (C), sodium (Na), and argon (Ar), respectively. Let's explore whether these elements can form higher oxides and their possible reactions with acids.

Carbon (C): Carbon is known to form several oxides, including carbon monoxide (CO) and carbon dioxide (CO2). However, carbon does not form higher oxides beyond carbon dioxide. Carbon dioxide is a stable oxide and does not react with most acids. However, it can react with certain bases, such as water, to form carbonic acid (H2CO3).

Sodium (Na): Sodium is a highly reactive metal and readily forms oxides. Sodium can form higher oxides such as sodium peroxide (Na2O2) and sodium superoxide (NaO2). Sodium peroxide reacts with water to form sodium hydroxide (NaOH) and hydrogen peroxide (H2O2). Sodium superoxide reacts with water to form sodium hydroxide (NaOH) and oxygen (O2).

When sodium oxides react with acids, they typically form salts and water. For example, sodium peroxide reacts with hydrochloric acid (HCl) to form sodium chloride (NaCl) and water (H2O). The reaction can be represented by the following equation:

2Na2O2 + 4HCl → 4NaCl + 2H2O + O2

Argon (Ar): Argon is a noble gas and does not readily form compounds or oxides. It is chemically inert and does not react with acids or other substances under normal conditions. Therefore, argon does not form higher oxides and does not react with acids.

In summary, carbon can form oxides such as carbon monoxide and carbon dioxide, but it does not form higher oxides. Sodium can form higher oxides like sodium peroxide and sodium superoxide, which can react with acids to form salts and water. Argon, being a noble gas, does not form oxides or react with acids.
