Question

what are oxide ? write example of amphoteric oxide and mixed oxide ?

Answer 1

Explanation:

Oxides are a chemical compound with one or more oxygen atoms combined with other elements

Types of oxides

1) Acidic oxide: oxides are oxides of nonmetals.

1) Acidic oxide: oxides are oxides of nonmetals.example : SO2 ,CO2,SO3

1) Acidic oxide: oxides are oxides of nonmetals.example : SO2 ,CO2,SO32) basic oxides: These are oxides of metals CaO,MgO,Na2O

1) Acidic oxide: oxides are oxides of nonmetals.example : SO2 ,CO2,SO32) basic oxides: These are oxides of metals CaO,MgO,Na2O3) Amphoteric oxides: Which shows both basic as well as acidic properties.

Amphoteric Oxide

It shows the characteristics of both an acid as well as a base. It reacts with both alkalis as well as acids. For example, zinc oxide acts as an acidic oxide when it reacts with concentrated sodium hydroxide. However, it acts as a basic oxide while reacting with hydrochloric acid.

Answer 2

Answer:

Oxides are binary compounds formed by the reaction of oxygen with other elements. Oxygen is highly reactive in nature. They react with metals and non-metal to form oxides.

Examples of amphoteric oxides are zinc oxide and aluminum oxide.

Mixed Oxides

Examples of these include: Lead dioxide (PbO2) and lead monoxide (PbO) combine to form the mixed oxide Red lead (Pb3O4). In another example, we can see that Ferric oxide (Fe2O3) and ferrous oxide (FeO) combine and form the mixed oxide Ferro-ferric oxide (Fe3O4).
