Zorluk: Çok zorOxygen, Ozone, and Classification of Oxides

Match each of the following oxides with its correct chemical classification and characteristic chemical behavior.

  • Dinitrogen monoxide (N2O\text{N}_2\text{O})Neutral oxide that exhibits no acid-base properties and does not form salts with acids or alkalis.
  • Barium peroxide (BaO2\text{BaO}_2)True peroxide containing the O22−\text{O}_2^{2-} ion, reacting with cold dilute acids to yield hydrogen peroxide (H2O2\text{H}_2\text{O}_2).
  • Lead(IV) oxide (PbO2\text{PbO}_2)Dioxide containing oxidation state +4, acting as a strong oxidizing agent and liberating chlorine gas when heated with concentrated hydrochloric acid.
  • Aluminium oxide (Al2O3\text{Al}_2\text{O}_3)Amphoteric oxide that reacts with both aqueous acids and strong bases to form salts and water.

Cevap

Dinitrogen monoxide matches as a neutral oxide; Barium peroxide matches as a true peroxide producing hydrogen peroxide with cold dilute acid; Lead(IV) oxide matches as a dioxide acting as an oxidizing agent to liberate chlorine gas from concentrated hydrochloric acid; Aluminium oxide matches as an amphoteric oxide reacting with both acids and bases.
The correct pairings accurately distinguish between oxide classes: dinitrogen monoxide is neutral, barium peroxide contains the peroxide anion yielding hydrogen peroxide with dilute acids, lead(IV) oxide is a dioxide acting as an oxidizing agent with concentrated hydrochloric acid, and aluminium oxide displays amphoteric properties by reacting with both acids and bases.

Adım Adım Çözüm

1
Analyze Dinitrogen monoxide (N2O\text{N}_2\text{O})
Identify that oxides of non-metals like N2O\text{N}_2\text{O} and CO\text{CO} are neutral and do not form salts with acids or bases.
Classification based on acid-base reactivity.
2
Differentiate between peroxides and dioxides using Barium peroxide (BaO2\text{BaO}_2) and Lead(IV) oxide (PbO2\text{PbO}_2)
True peroxides like BaO2\text{BaO}_2 contain the O22−\text{O}_2^{2-} ion and produce H2O2\text{H}_2\text{O}_2 with dilute acid. Dioxides like PbO2\text{PbO}_2 contain metal in +4 oxidation state and act as oxidizing agents, yielding Cl2\text{Cl}_2 gas with concentrated HCl\text{HCl}.
Oxidation state analysis and chemical reaction product test.
3
Analyze Aluminium oxide (Al2O3\text{Al}_2\text{O}_3)
Determine that metallic oxides of group 13 like Al2O3\text{Al}_2\text{O}_3 dissolve in both acids (forming Al3+\text{Al}^{3+} salts) and strong bases (forming aluminate complex salts), confirming amphoterism.
Amphoteric nature of specific metal oxides.
