Question

Складіть формули речовин: кальцій оксид, калій оксид, фосфор(V) оксид, фосфор(III) оксид, барій оксид, цинк оксид, бор оксид, алюміній оксид. Які із цих оксидів основні, які кислотні, а які амфотерні? ​

Answer 1

Ответ:

Объяснение:

основні -

CaO - кальцій оксид

K₂O - калій оксид

BaO -барій оксид

кислотні -

P₂O₅ - фосфор(V) оксид

P₂O₃ - фосфор(III) оксид,

B₂O₃ -бор оксид - більш кислотний \має слабкі ознаки амфотерності

амфотерні -

ZnO - цинк оксид

Al₂O₃ -алюміній оксид.

Answer 2

Chemical Formulas of Oxides:

Here are the chemical formulas for the given oxides:

- Calcium oxide: CaO - Potassium oxide: K2O - Phosphorus(V) oxide: P2O5 - Phosphorus(III) oxide: P4O6 or P4O10 (both are possible) - Barium oxide: BaO - Zinc oxide: ZnO - Boron oxide: B2O3 - Aluminum oxide: Al2O3

Classification of Oxides:

Oxides can be classified into three main categories based on their chemical behavior: basic (alkaline), acidic, and amphoteric.

Basic Oxides: Basic oxides are oxides that react with water to form bases. They have a tendency to donate hydroxide ions (OH-) in aqueous solutions. Some examples of basic oxides from the given list are: - Calcium oxide (CaO) - Potassium oxide (K2O) - Barium oxide (BaO) - Zinc oxide (ZnO) - Aluminum oxide (Al2O3) (amphoteric)

Acidic Oxides: Acidic oxides are oxides that react with water to form acids. They have a tendency to donate hydrogen ions (H+) in aqueous solutions. An example of an acidic oxide from the given list is: - Phosphorus(V) oxide (P2O5)

Amphoteric Oxides: Amphoteric oxides are oxides that can exhibit both acidic and basic properties. They can react with both acids and bases. An example of an amphoteric oxide from the given list is: - Aluminum oxide (Al2O3)

It's important to note that the classification of oxides as basic, acidic, or amphoteric is based on their behavior in water. The classification may vary in different contexts or under different conditions.
